bitbake-prserv: replace deprecated optparse by argparse

optparse is deprecated since Python 2.7

Note that this is neither supposed to change the options
supported by bitbake-prserv nor the way they are interpreted.

Note that in the "--help" output, long options are now reported
for example as "--host HOST" instead of "--host=HOST" but
both are equivalent anyway, as they already were with optparse.
