Make compatfd fallback more robust
Be more friendly when signalfd() fails, and also add configure checks to detect
that syscall(SYS_signalfd) actually works. malc pointed out that some installs
do not have /usr/include/linux headers that are in sync with the glibc headers
so why SYS_signalfd is defined, it's #defined to _NR_signalfd which is not
defined in the /usr/include/linux header.
While this is a distro bug, it doesn't hurt to do a more thorough job in
detection.
