narrow: when writing treemanifests, skip inspecting directories outside narrow

This provides significant speed benefits when narrow and treemanifests are in
use, see the timing numbers below. Note that like previously, differences of <5%
are considered noise.

The below timing numbers are in the same style as previously (example:
ee7ee0c516ca). 'before' is 9db85644, and does not include that example commit's
improvements.
