fix sysvipc structures on powerpc

Browse source 
these have been wrong for a long time and were never detected or
corrected. powerpc needs some gratuitous extra padding/reserved slots
in ipc_perm, big-endian ordering for the padding of time_t slots that
was intended by the kernel folks to allow a transition to 64-bit
time_t, and some minor gratuitous reordering of struct members.
