gh-110033: Fix signal test_interprocess_signal() (#110035)

Browse Source 
Fix test_interprocess_signal() of test_signal. Make sure that the
subprocess.Popen object is deleted before the test raising an
exception in a signal handler. Otherwise, Popen.__del__() can get the
exception which is logged as "Exception ignored in: ...." and the
test fails.
