Remove the now-unneeded ifdeff'ery.

Makes sense:
epoll_wait()
Linux 2.6, glibc 2.3.2.
epoll_pwait()
Linux 2.6.19, glibc 2.6.
Which has made this available for 9 years.
This is not it, Pierrick :)
qemu ships its own copy of linux headers with all these
__NR_foo definitions. We don't have to deal with local
linux headers, we know exactly and precisely what we ship
and which targets defines which syscalls. Once all arches
has __NR_epoll_wait *in our copy of linux-headers*, we're
all set. No matter if it was 9 years ago or yesterday.
TARGET_NR_foo is what *we* know, - and it might be much
more fresh than the host kernel we're running on.
