[Bug 1466210] [NEW] don't gzip gtkdoc's devhelp2 files

[Stefan Sauer]

Public bug reported:

I am the upstream gtkdoc developer and maintainer and work on
https://bugzilla.gnome.org/show_bug.cgi?id=742404 that will be part of
the next gtk-doc release. With some luck I noticed that Ubuntu applies
gzip compression to some of gtkdoc's data files.

Please don't do this. While I can probably use popen for this case, I
cannot handle this for all possible cases (e.g. some distro using bzip2
instead). These files are only installed on developer machines and I
don't think the space saving are worth it. I'd believe most developers
rather get better performance.
