um: Add seccomp support
This brings SECCOMP_MODE_STRICT and SECCOMP_MODE_FILTER support through
prctl(2) and seccomp(2) to User-mode Linux for i386 and x86_64
subarchitectures.
secure_computing() is called first in handle_syscall() so that the
syscall emulation will be aborted quickly if matching a seccomp rule.
This is inspired from Meredydd Luff's patch
(https://gerrit.chromium.org/gerrit/21425).
