lttng-tools: Filter out regression testsuite on musl systems

regression testsuite does not run to finish on musl systems, some of
the issues seen

* python is OOM'ing which is fixed by asking for 8G memory for qemu
* It hits the timeout limits of ptest-runner even -t 2400 does not finish it
* Use make -j1 and running run-ptest script directly ( outside
  ptest-runner to avoid timeout limit) causes it to run forever

Lets disable this testsuite for musl systems for now.
