prservice.py: fix do_package with newer Python in Ubuntu 20.04
* with Ubuntu 20.04 which is using python 3.8 I'm seeing a lot of errors like:
ERROR: libxml2-2.9.10-r0 do_package: Can NOT get PRAUTO, exception No module named '_sysconfigdata'
not sure what caused this from python 3.8, but this seems to work
* PRserv is enabled with:
PRSERV_HOST = "localhost:0"
