Tiezhu Yang ece7f7c050 perf bench syscall: Add fork syscall benchmark
This is a follow up patch for the execve bench which is actually
fork + execve, it makes sense to add the fork syscall benchmark
to compare the execve part precisely.

Some archs have no __NR_fork definition which is used only as a
check condition to call test_fork(), let us just define it as -1
to avoid build error.
