py/gc: Adjust gc_alloc() signature to be able to accept multiple flags. 

The older "bool has_finaliser" gets recast as GC_ALLOC_FLAG_HAS_FINALISER=1
so this is a backwards compatible change to the signature.  Since bool gets
implicitly converted to 1 this patch doesn't include conversion of all
calls.
