Natanael Copa 7ea8f69a06 Fix user-data decompression on all shells ...

yash[1] and zsh does not handle 8-bit bytes in strings good. Work around it
by using printf ... | cmp ... to compare the header. This should be 100%
posix compatible.

Also fix some of the compression header magic bytes:

- unxz: Use octal aas the string '\3757zXZ\000' was misinterpreted by some
  shells.
- lzma: the third byte represents compression mode[2], and we want
  support all compression modes not only '8', so we only check the first
  three bytes instead of 4.
