  bpo-30320: test_eintr now uses pthread_sigmask() (#1523)

Rewrite sigwaitinfo() and sigtimedwait() unit tests for EINTR using
pthread_sigmask() to fix a race condition between the child and the
parent process.

Remove the pipe which was used as a weak workaround against the race
condition.

sigtimedwait() is now tested with a child process sending a signal
instead of testing the timeout feature which is more unstable
(especially regarding to clock resolution depending on the platform).
