This adds ${_PBUILD} and ${_PFETCH} to set the relevant user when doing
adastrap operations; they expand to the relevant sudo/doas command if
PORTS_PRIVSEP=Yes, or nothing if PORTS_PRIVSEP=No, so it works in both
cases.

Uses the old 'sudo tee destfile > /dev/null' trick for the bit where it
needs to work in a pipeline.

ok?
