Cleanups to run_tests.sh script (#8337)
Bugfix:
* Use the `pub` from within the built Dart SDK (not whatever's on
  `$PATH`, if anything).

A few minor improvements:
* Allow running from below the src/ buildroot dir, as it's often
  convenient to work from within the flutter/engine git dir.
* Echo test name before running, for slightly better debuggability.
* Minor line-wrapping for readability.
