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.
