cmake: determine list of extra built-ins dynamically

Browse source 
In 0a21d0e089 (Makefile: mark git-maintenance as a builtin,
2020-12-01), we marked git-maintenance as a builtin in the Makefile, but
forgot to do the same in `CMakeLists.txt`.

Rather than always play catch-up and adjust `git_builtin_extra`
manually, use the `BUILT_INS` definitions in the Makefile as
authoritative source and generate `git_builtin_extra` dynamically.
