perf test: Run parallel tests in two passes

In pass 1 run all tests that succeed when run in parallel. In pass 2
sequentially run all remaining tests that are flagged as
"exclusive". Sequential and dont_fork tests keep to run in pass 1.
Read the exclusive flag from the shell test descriptions, but remove
from display to avoid >100 characters. Add error handling to finish
tests if starting a later test fails. Mark the task-exit test as
exclusive due to issues reported-by James Clark.
