test-runner: allow regex for verbose option

The glob match was completely broken for --verbose because globs
are actually path matches, not generally for strings. Instead
match based on regular expressions.

First the verbose option was fixed to store it as an array as well
as write any list arguments into the kernel command line properly
(str() would include []). This has worked up until now because the
'in' keyword in python will work on strings just as well
as lists, for example:

>>> 'test' in 'this,is,a,test'
True

Then, the glob match was replaced with a regex match. Any exceptions
are caught and somewhat ignored (printed, but only seen with --debug).
This only guards against fatal exceptions from a user passing an
invalid expression.
