find: Allow -type d without statting everything.

fts(3) detects directories even in FTS_NOSTAT mode (so it can descend into

No functional change is intended, but find commands that use -type d but no
primaries that still require stat/lstat calls make considerably fewer system
calls.
Add some missing .Nm for newer syscalls in existing man pages.
