Add missing ppc64-linux and s390x-linux syswraps existing on other arches

This update adds following ppc64le and s390x syswraps:
 - sys_msgctl
 - sys_semctl
 - sys_semtimedop
 - sys_sethostname
 - sys_shmctl
 - sys_sigpending
 - sys_stime

This update adds following ppc64le syswraps:
 - sys_setns

This update adds following s390x syswraps:
 - sys_bpf

Blacklist the shmctl05, as it is a long running one.  It does
pass on all architectures afaics, but needs a relatively high
LTP_TIMEOUT_MUL setting. So, let's skip that one.
