bfstd: New {error,errno}_is_like() functions

We used to have is_nonexistence_error() to consistently treat ENOENT and
ENOTDIR the same.  Recently, we started considering EFAULT the same as
ENAMETOOLONG on DragonFly BSD to work around a kernel bug.  Unify both
of these behind a more generic interface.
