userspace/ppsi: uplift ppsi with compliance

This commit includes the commit in ppsi
"Support E2E build without P2P. Saves 5kB in wrpc-sw"
However when the option "Avoid building P2P code" is not enabled in
the ppsi's dot-config then I'm getting zeros in the wr_mon or the ppsi exits
with the message:
ERROR: failure in "clock_settime": Invalid argument
