RNA: use 1/0 for move layers operator

internal api Consistency.

For the records, I suspect there are still a few cases of this. I found
this by chance (moving an object to a different layer), and I ran into
the previous one (fixed by Campbell) as well (by adding a cube).

Anyways, since it only happens when building with crash on asserts is
not a big issue. But by the time we change RNA to use bool instead of
int it would be nice to do a call for test to prevent those breaks.
