[PATCH RFC] mirrors: Switch glibc and binutils to use shallow mirror tarballs

[Richard Purdie <richard.purdie@linuxfoundation.org>]

These two repositories are large and overload our downloads server as a
premirror but the recipes are easier to maintain as git urls. Compromise
and use shallow clones for them.

In order to be effective, we need premirror entries on where to find
the shallow mirror tarballs.
