Subject: [PATCH 1/1] yum.misc.decompress() to handle uncompressed files
(RhBug:1895059)
The underlying libdnf function is capable to handle even uncompressed
files - so now uncompressed files are just copied to the destination.
Also unused fn_only parameter of the function was removed.
This fixes issue with "reposync -m" command when the group metadata file
in the repository is a plain xml file (not compressed).
