daemon: start Quagga with default user/group names

Allow native distribution packages to run with their default user
and group names by no longer forcing "-u root -g root" on any of
the Quagga daemons' command lines.

This should continue to allow hand-compiled and/or "side-loaded"
Quagga software to run as root, if configured to do so at build
time.
