Revert "gnome-extra/libgda: 5.2.5 version bump"

This reverts commit 880699bb699214cac6e4f6e99a369eeccca4ca43.

Unauthorized commit with the following issues:

* USE=vala completely broken.
  "configure: WARNING: unrecognized options: --enable-vala" should
  have given a hint, after blindly dropping a patch we had to fix
  this case properly.
* Wrong sqlite minimum dep

Issues inherited from old version, that would be routine for
maintainer to check over and fix:

* Missing glib-utils build dep
* Ineffective JRE 1.8 support patch (configure only is patched, but
  eautoreconf is called after patching)
* Lack of GNOME2_EAUTORECONF="yes" usage over manual autotools
  inherit and eautoreconf call (leads to double elibtoolize call,
  which is problematic for some edge cases and could QA warn)

Fixing vala takes some effort, hence a revert of commit that shouldn't
have been pushed (not acked by maintainer) for now, not immediate
follow-up fixes.
