alpha: Wire up missing/new syscalls

This wire up the: fallocate, timerfd_create, timerfd_settime,
timerfd_gettime, signalfd4, eventfd2, epoll_create1, dup3, pipe2,
inotify_init1, preadv, pwritev and rt_tgsigqueueinfo syscalls for
the alpha port.

For umount2, alpha have an "old" and "new" version called: oldumount and
umount; so ignore umount2.

Rebased on top of 6e17e8b9fb74b9fb9f6ea331f7f4a049c5b4c4b8 by Matt
Turner.
