configure.ac: Add the check for the ffs function

Browse Source 
When Cogl was sharing Clutter's configure script, it had a check for
the ffs function of libc so that it can provide a fallback if it is
not available. This fallback was missed in the split out so Cogl would
end up always using the fallback.
