The reason why it is done this way in syscalls.stp is that in the kernel
sys_epoll_create is just a wrapper around sys_epoll_create1.  This way we
ignore the sys_epoll_create call, and only catch the sys_epoll_create1 call on
kernels with sys_epoll_create1.

Unfortunately, as bug #11424 notes, '!' (optional and sufficient) doesn't work
for kprobe.function probes.  So, the above logic will be difficult to duplicate
in tapset/nd_syscalls.stp.
