Move FilePathWatcher class from chrome/browser/... to content/common...

The service process needs FilePathWatcher, and with this change I
got rid of the dependency on BrowserThread which allows it to be moved to common/...
I also tried my hand at a kqueue impl on the Mac, but failed.
See http://code.google.com/p/chromium/issues/detail?id=54822#c13 for details.
