glsl: Refactor uniform block parser rules.

The existing code has a lot of duplication; the only difference between
the two cases is whether we merge in an additional layout qualifier.

Apparently creating a layout_qualifieropt rule that can be empty causes
a lot of conflicts and confusion.  However, refactoring out the guts of
the ast_uniform_block creation works fine.
