gmacros: Use __typeof__ when compiling with Clang

Browse Source 
Just like gcc, clang has supported `__typeof__` for a long time, so
allow it to be used. This fixes compilation of `gio/gcredentials.c` on
macOS (which uses clang by default).

I don’t know which version clang started supporting `__typeof__` in, so
there’s no version check. One can be added in future if there are
problems.

This fixes commit 5b2bee3f539.
