I tricked myself into thinking that deadlock detection is off by default in TSan by looking at the default value of the detect_deadlocks flag and outdated docs. (Created a pull request to update docs.)
I even managed to confuse others: https://groups.google.com/forum/#!topic/thread-sanitizer/xYvnAYwtoDk
However, the default value is overwritten in code (TSan_flags.cc:InitializeFlags). The TSan/deadlock tests also rely on this
This changes aligns the default value of the flag with the actual default behavior.

Summary:
Always quote suppressions files given to *_OPTIONS.
This will make it not break when given full Windows paths (otherwise,
parsing would stop after the drive's letter + ':').
Also fix one or two cases where the suppression files' extensions were
not *.supp.

The tsan's deadlock detector has been used in Chromium for a while;
it found a few real bugs and reported no false positives.
So, it's time to give it a bit more exposure.
