[sleepy.penguin] [PATCH] test_epoll: switch test_dup_and_fork to exit!

[Eric Wong <normalperson@yhbt.net>]

exit! is preferable for forked processes in tests since
exit may fire at_exit handlers for tests depending on
which test suite or version of Ruby is loaded.

This was problematic in minitest 5.0.8 but not 4.3.2

 Note: we already use exit! in many places in tests
