Revert "libbsd: replace with nbcompat"

This reverts commit 480434f7eeefed7026dbbd11a4a0b1e4bfc1f137.

netbsd.compat does not provide include files that are provided by libbsd [1], and it
encumbers its transitive dependents with an obligatory include file that setups
BSD-compatible C environment [2].
