thread_pthread.c: use eventfd instead of pipe on Linux

Based on r64478, any regular user creating more than 1024 pipes
on Linux will end up with tiny pipes with only a single page
capacity. So avoid wasting user resources and use lighter
eventfd on Linux.

Pretty trivial this time around. Will commit in a few days.
