uma dbg: flexible size for slab debug bitset too

Recently (r355315) the size of the struct uma_slab bitset field us_free
became dynamic instead of conservative.  Now, make the debug bitset
size dynamic too.  The debug bitset is INVARIANTS-only, so in fact we
don't care too much about the space savings that results from this, but
enabling minimally-sized slabs on INVARIANTS builds is still important
in order to be able to test new slab layouts effectively.
