examples/ephiperfifo.c: simplify signal handler

The signal handler registered for SIGINT is only handling SIGINT
so there isn't much need for inspecting the signo.  While there,
rename the handler to be more specific.

g_should_exit should really be of sig_atomic_t type, but relying
on autoconf in the examples seems like a bad idea so keep that
for now.
