main.cxx: add LKET's tapsets into stap's default tapsets search path

update lket man page to refect the new tapset search path

syscalls.stp: make sys_acct, sys_add_key, sys_keyctl and sys_modify_ldt optional on ppc64 since they are weak symbol.

ppc64/syscalls.stp: remove syscall.acct, syscall.add_key and syscall.umask since they are already defined in syscalls.stp
