wlr_shm: make wl_global public

Browse source 
I wish to use a allowlist of globals for my security context
implementation rather than a blocklist, which means I need access to
the wl_shm global in order to allowlist it.

I think using a allowlist will make it harder for me to accidentally
expose globals to a security context that were meant to be restricted.
