run-tests: teach _processoutput to handle multiple lines of churn

Instead of treating expected output as happening in a precise order,
and assuming that if a line is missing it will never happen,
assume that expected output is a prioritized list of likely matching
lines.

This means that if:

 foo/bar (glob)
 baz/bad (glob)

changes to:

 baz/bad
 foo/bar

instead of generating:

 baz/bad
 foo/bar

For which we've lost both (glob) markers,
we will match both lines and generate:

 baz/bad (glob)
 foo/bar (glob)

This retains any special annotations we have for lines.
