The tst_checkpoint_wait() has a single use in the source tree and that
is testcases/lib/tst_checkpoint.c which is binary wrapper around
checkpoints so that we can use them in shell scripts as well, which is
pretty cool btw. And I think that we should retry on EINTR there as
well.

Also there does not seem to be test relying on checkpoints being
interrupted by signals and I would like to avoid this pattern ideally as
asynchronous events such as signals interrupting functions is something
rather counter intuitive.
