Revert of Linux: Depend on liberation-fonts package for RPMs. (patchset #1 id:1 of https://codereview.chromium.org/1358903005/ )

Reason for revert:
Fedora 21 is still broken.

Original issue's description:
> Linux: Depend on liberation-fonts package for RPMs.
>
> The previous try in r342645 was reverted because Fedora did not have a
> liberation-fonts virtual package. Fedora has since added the missing
> virtual pacakge per our request to supported distros - Fedora 21 and
> newer.
>
> So now we can fix the mismatch vs .debs, which added this dependency in
> r342854.
