ttcn3-bts-test: add --no-warnings to bpftrace
Since switching to debian 13 and having bpftrace 0.23.2 instead of
0.17.0, bpftrace is constantly printing warnings. Turn off warnings by
default so we don't end up filling up the disk space of jenkins runners
while ttcn3-bts-test runs for >2h.
We can turn on warnings in copies of the main jenkins job for
development, while also ensuring that we only run a few tests instead of
the whole testsuite.
Warnings look like this:
