warn_collector: handle non-fatal signals

If we pause the process (standard SIGSTOP/SIGCONT), the read() on the
inotify handle gets angry and aborts.  This can happen if you ctrl+z
the program, or if you attach to it with strace.  This is undesirable,
so ignore EINTR errors from the read().

BUG=None
TEST=ran `./warn_collector --test` and hit ctrl+z then fg
