[oe] [PATCH v2] lib/oe/unpack.py: fix uncompressing .gz .bz2 or .xz

[Eric Bénard]

* Actually, the uncompressed file is written into the source
path instead of the destination path.
* By also removing the source path, this patch should fix this problem.
* An other fix could be to not uncompress to stdout but let gunzip|bunzip2|
xz uncompress directly to the file.
