Don't link explicitly with libwmem, it's already in libwireshark and the symbol

doubling leads to all sorts of very subtle badness (including test failures due
to funny internal assertions because the two wmems have mismatching state).

Make wmem_init and wmem_cleanup PUBLIC instead of LOCAL so that they don't get
stripped and don't cause a link failure when trying to build oids_test (now that
it's not linking with libwmem explicitly). There is possibly a better way to fix
this, but I'm not sure what it is.
