CTest: Clean up stdout and logfile output for Pass/Fail regex

For pass regex, display only the element that was found, rather
than all elements
Rename loop variable for fail regex, from pass to fail
For consistency, add space in output for pass
Add tests that find and don't find PASS_REGULAR_EXPRESSION, and a test
that finds FAIL_REGULAR_EXPRESSION, whose LastTest.log files are checked
using *-check.cmake.
