A set of system call defines like __NR_alarm, __NR_ioperm,
__NR_modify_ldt, __NR_time, __NR_utime is missing in aarch64
kernel as of 4.18 kernel version.
Add corresponding definitions so system call related probes
would compile. Tested with nd_syscalls-all-probes.stp.

A set of system call defines like __NR_pkey_alloc, __NR_pkey_free
__NR_pkey_mprotect are missing in powerpc64 kernel as of 4.14 kernel
version.
Add corresponding definitions so system call related probes
would compile. Tested with nd_syscalls-all-probes.stp.

Here is error that I get with latest systemtap on nxp p5020
powerpc64 machine. But I think the error is common for all
older kernels that would not have those system calls yet:
