ttcn3-fr-tests: Disable junit-xml generation for FRNET_Tests

FRNET_Tests is not a test suite, but just a stub against which we
execute FR_Tests.  Hence, we don't want it to generate a junit-xml,
as that doesn't contain any errors and only upsets our jenkins
test results analyzer, assuming the tests have failed.
