Move the use of md5s for recording filesystem file integrity
checks to sha256 hashes as they're preferred due to being
less likely to produce clashing hashes. In the process
generalise some of the wording to use the more generic
hash term.

`egrep` has been deprecated in GNU grep since 2007,
and since 3.8 it emits obsolescence warnings:

Coreutils command nproc can be used on Linux and BSD to count the number of
available CPU cores. Use this instead of relying on the parsing of the
Linux specific proc file system.

For a long time now, 'sb' has been deprecated as a command in favor of
using 'host' for the sandbox hostfs interface, switch.

As far as this patch series has been applied, all the tests should
pass. So update the test result summary.

Given 0dc1bfb7302d ("fs: fat: cannot write to subdirectories") we have
changed how the FAT code works from creating the illegal file "./file"
and instead rejecting the path.  The correct behavior would be to write
"file" to "." but not writing an illegal file is a step in the right
direction.  For now, update the expected output to account for the
failure.

Added a simple ls to a nonexistent directory for test 1.
In case the driver is broken for a nonexistent directory, U-boot
might crash.

Here is an example failed output:

=> # Test Case 1 - ls
=> ext4ls host 0:0
<DIR>       4096 .
<DIR>       4096 ..
<DIR>      16384 lost+found
<DIR>       4096 SUBDIR
      2621440000 2.5GB.file
         1048576 1MB.file
=> # In addition, test with a nonexistent directory to see if we crash.
=> ext4ls host 0:0 invalid_d
** Can not find directory. **
./test/fs/fs-test.sh: line 161: 25786 Segmentation fault      (core dumped) $UBOOT  <<EOF

Subsequent tests will fail if U-boot crashes.

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

The previous commit fixed a problem in FAT code where going back to the
root directory using '..' wouldn't work correctly on FAT12 or FAT16.
Add a test to exercise this case (which was once fixed in commit
18a10d46f26 "fat: handle paths that include ../" but reintroduced due to
the directory iterator refactoring).

This test only very barely catches the problem - without the fix the
size command still gives valid output but the additional spurious
"Invalid FAT entry" error message makes it not get caught in the
'egrep -A3 ' output. I tried to make a proper test that grows the root
directory to two clusters lots of with dummy files but that causes the
write tests to crash the sandbox totally...
