Remove remaining unused imports in webkitpy.

Remove unused imports in webkitpy.

It seems like I did this before, but there were apparently still
a bunch of unused imports.

This CL also sorts imports in files where unused imports are removed.

I checked that this shouldn't remove any imports of webkitpy.common.version_check.
