Nicholas Nethercote e7f10a07fd Bug 1293603 (part 2) - Make Run() declarations consistent. r=erahm.
This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.

As a result of these changes, I had to add |override| to a couple of other
functions to satisfy clang's -Winconsistent-missing-override warning.
