Subject: [PATCH] test: forbid `common.mustCall*()` in process exit handlers

`common.mustCall()` and `common.mustCallAtLeast()` need to be called
before process exit handlers to work because checks are done inside a
process exit handler. Detect if being used inside a process exit handler
and throw.
