For cases when systemap module compilation happens on host in
cross-compilation mode, and it is desirable to minimize systemtap
presense on target we need to have just smallest possible set of
utilties that are required to run compiled modules.

Introduce new "translator" PACKAGECONFIG, if it is not set
it would mean that just minimal set of run-time utilities will
be included in the package.

For run-time only systemtap build variant use
PACKAGECONFIG_pn-systemtap = "" or
PACKAGECONFIG_pn-systemtap = "monitor"
