cmd: strings: interpret second argument as a byte count

The help text advertises "<addr> [byte count]" but do_strings()
stores argv[2] directly into last_addr and the loop condition tests
"addr < last_addr", i.e. it treats the value as an absolute end
address. When invoked as documented (e.g. "strings 0x40000000
0x100") the loop condition fails immediately because the supplied
count is far below start_addr, and the command prints nothing.

Compute last_addr as start_addr + hextoul(argv[2], NULL) so the
argument is used as a length in bytes, matching the help. The
existing repeat-mode fixup (last_addr = addr + (last_addr -
start_addr)) continues to preserve the same byte-count window
across CMD_FLAG_REPEAT.
