perf/benchmark: add a new benchmark for seccom_unotify
The benchmark is similar to the pipe benchmark. It creates two processes,
one is calling syscalls, and another process is handling them via seccomp
user notifications. It measures the time required to run a specified number
of interations.
$ ./perf bench sched seccomp-notify --sync-mode --loop 1000000
# Running 'sched/seccomp-notify' benchmark:
# Executed 1000000 system calls
Total time: 2.769 [sec]
