qlit: Change compound literals to initializers 

The QLIT_QFOO() macros expand into compound literals.  Sadly, gcc
doesn't recognizes these as constant expressions (clang does), which
makes the macros useless for initializing objects with static storage
duration.

There is a gcc bug about it:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71713

Change the macros to expand into initializers.
