This adds s2tc as an input to mesa, and uses a mesa-without-s2tc package
as an input to s2tc to solve a cyclic dependency.
The resulting s2tc package does *not* link to any libraries in the
mesa-without-s2tc package (it's not a requisite as per "guix gc -R"), so
this should be safe, as in the user won't end up with two different
libGL images in memory.

Please postpone reviewing this! (Sorry if I wasted anyone's time.)
I was planning to do all the dlopen() patching later on in one commit,
but realized that it means I will be adding a phase lambda that
references the 's2tc' input, after which the 'mesa-without-s2tc' package
breaks because it simply inherits from the full 'mesa' package. (I
would have to hackishly take out that lambda from the phases again to
make it work...)
I'm pondering on a solution using a much more minimal 'mesa-for-s2tc'
package. I might even get away with only installing the libGL headers
in the output of that package, without doing any compilation at all,
since I think s2tc needs only the headers...

Here's the updated patch, which adds a mesa-headers package, and fixes
the dlopening of s2tc.

LGTM, but please make the addition of s2tc to mesa a second patch.

Could you expound a bit, giving a bit more context?
Thanks!
