  tests: fix spurious failures due to ignored signals
  
  * tests/defs (is_blocked_signal): New function.
  * tests/parallel-tests-interrupt.test: Do not try to use/trap
  signals that are ignored by the parent shell: they will be
  ignored by all the child processes too.
  * tests/self-check-exit.test: Likewise.
  * tests/self-check-cleanup.test: Likewise, and do few minor
  improvements and extensions since we are at it.
