seccomp: Adjust list of allowed syscalls for armv6l, armv7l

Browse source 
It looks like glibc commonly implements clock_gettime(2) with
clock_gettime64(), and uses recv() instead of recvfrom(), send()
instead of sendto(), and sigreturn() instead of rt_sigreturn() on
armv6l and armv7l.

Adjust the list of system calls for armv6l and armv7l accordingly.
