utils: do not hardcode postgres version

PMG::Utils::lookup_real_service_name is only called
for translating the service names provided as arguments
to PMG::API2::Nodes::syslog (for fetching the journal
for specific units). Instead of hardcoding the
version getting it with a call to `psql` seems justified.
