* gnu/packages/fontutils.scm: Update all sources hosted on freedesktop
to fetch tarballs via https. freedesktop.org appears to have updated
recently to redirect all http to https. As an exception, we leave
pkg-config like it is, because pkg-config is needed to build gnutls,
and without gnutls we can't download https URLs.

and actions are looked for under /etc/polkit-1.

documentation.

rules in the system profile. Arrange to look for the setuid helper in
/run/setuid-programs. Fix introspection installation.
