Update stale links to `gmock_cook_book.md`.
I'm a new googletest user and found these links broken when reading the documentation.

Fix some issues when running fuse_gmock_files.
The module path should be updated before importing `fuse_gtest_files`, since
the script may not run from the googletest repo root. We also need a non-frozen
set in order to track progress.

Fix `-Wgnu-zero-variadic-macro-arguments` in GMock
Passing zero arguments to the variadic part of a macro is a GNU
extension and triggers warnings when build projects using GMock with
`-pedantic`.
- Fix uses of `GMOCK_PP_INTERNAL_16TH` to always receive at least 17
arguments. (this was triggered when `GMOCK_PP_NARG` or `GMOCK_PP_HAS_COMMA`
were used with an argument containing no commas).
- Fix `GMOCK_PP_HEAD` to append a dummy unused argument so that
`GMOCK_PP_INTERNAL_HEAD` always has two arguments.
