Reduce 2029-contended-monitors iteration count

... for debuggable runs to prevent timeouts.

This required some other minor changes since we determine whether we
are debuggable only at run-time, and some of the long lock hold times
are no longer feasible with loower iteration counts. We want to keep
the output constant, so we reduced iteration consistently for all
configurations.

Unfortunately, the new dependency on libarttest causes this to
throw under atest. Catch whatever error/exception that is, and
make conservative assumptions for that case.

Test: testrunner.py --host -b -t 2029-contended-monitors
