Ninja: Fix RC language depfile generation with cmcldeps

In commit v3.7.0-rc1~275^2 (Ninja: Use full path for all source files,
2016-08-05), the source path was changed to use an absolute path.
Inside of `cmcldeps` for `.rc` file compilation, it uses a separate
argument for the path to the source file.  This ended up causing
`cmcldeps` to transform the following call:

    cmcldeps.exe RC source.rc ... C:/full/path/to/source.rc


    ... C:/full/path/to//Tc source.rc

which is invalid.  Update the source filename to use the full path to
the source file so that the path is replaced properly.
