test/includes: Use ${gen_cdefs} when pre-processing headers
Now that uv.h is directly being included, pre-processing of
test/includes/pre/uv.h fails on Linux with

    In file included from «SRCDIR»/neovim/test/includes/pre/uv.h:1:
    In file included from /usr/include/uv.h:62:
    /usr/include/uv/unix.h:72:11: fatal error: 'uv/pthread-barrier.h' file not found
    # include "uv/pthread-barrier.h"
              ^~~~~~~~~~~~~~~~~~~~~~
    1 error generated.

This happens because we're missing -D_GNU_SOURCE (part of ${gen_cdefs}),
which makes the pthread_barrier_* functionality visible.
