ttcn3-bts-test/jenkins.sh: set mp_pcuif_version

OsmoBTS currently uses PCUIF v.10 but will move to v.11 soon. (see
Depends). Unfortuantely this means that we have to execute the TTCN3
testsuite in master with PCUIF v.11 and in latest with PCUIF v.10. This
will be the case until the current master becomes the new latest on the
next release.
