Cerbero GStreamer recipes are now built with Meson

Sure, I can hack the file (along with the flags and everything) but it still doesn't work because there are lots of incompatibilities.  For example, this is the first error I see after `./cerbero-uninstalled build gstreamer-1.0`

I think you forgot to run bootstrap? Anyway, bootstrap fails with
clang while building m4, so I built the build-tools with gcc (doesn't
matter what they are built with). Then, the first failure was in
gobject-introspection:

./g-ir-compiler --includedir=. --includedir=./gir --includedir=.
--includedir=. --includedir=./gir --includedir=. gir/cairo-1.0.gir -o
gir/cairo-1.0.typelib
clang-6.0: error: unknown argument: '-fcf-protection'

    spawn(cmd, dry_run=self.dry_run)

    % (cmd, exit_status))
distutils.errors.DistutilsExecError: command 'ccache' failed with exit status 1

So that either needs to be fixed, or introspection needs to be
disabled everywhere as a start. Overall, I think this is probably
doable. The main issues will be autotools recipes, but any meson
recipes should be fine.
