[LTP] [PATCH v3] doc: update syscalls statistics

[Andrea Cervesato]

I forgot to mention that there are syscalls like "cachectl" which are 
MIPS specific.
At the same time, "restart_syscall" is supposed to be used for internal 
usage only.

I left them there, but maybe they need to be blacklisted as well.
