inhibit: improve performance of transaction wrapping

Before this patch, transaction wrapping was the most expensive part of inhibit
computation wise. This patch changes the revset that we use in the transaction
wrapping to make it ~50x faster to compute:


revset #0: obsolete() - hidden()
0) wall 0.000214 comb 0.000000 user 0.000000 sys 0.000000 (best of 11209)

vs

revset #0: (not hidden()) and obsolete()
0) wall 0.010965 comb 0.010000 user 0.010000 sys 0.000000 (best of 237)
