[src/trunk]: src/usr.bin/make make(1): make a few more bool expressions more ...

description:
make(1): make a few more bool expressions more precise
The previous version of lint(1) from a few hours ago didn't catch all
occurrences. And even the current one doesn't catch everything.
Function arguments and return types still need some work. The "return
quietly" from shouldDieQuietly still implicitly converts from int to
_Bool.
No functional change.
