bitbake: fetch2: fix unpack of .xz files 

If a file ends with .xz, it currently gets overwritten during unpack:
The decompress command for .xz files is:
  'xz -dc %s > %s' % (file, efile)
and as efile == file, we end up overwriting file (the source).

Fix this by adding .xz to the list of suffixes that that need to
be removed from a file name for an extract command, leaving the
bare file name. Now, for a given file foo.xz,
file == foo.xz and efile == foo, similar to how .gz .bz2 and .Z
files are treated.

(Bitbake rev: 2cd2d0a48e12ab4358fb967eaf7a56c17993f48d)
