Exception on unencodable (file)name

Some code generators (e.g. Template engines) can produce fake module names. Recently a test in the Tornado test suite has started failing with a non-ascii fake module name and a C locale:
https://travis-ci.org/tornadoweb/tornado/jobs/176023596#L1120

I would suggest that coverage.py catch UnicodeEncodeError at that point and consider the file as non-existing.

Fixed in 696d259b6031 (bb). Figuring out how to reproduce and test the problem was the biggest challenge!
