Fix gitignore

- `*build*/` is not needed because Meson puts a .gitignore in builddir
already.

- `meson/` why?

- `/gst*` is too wide, it includes e.g. gst-env.py, list symlinks
explicitly instead.

- `subprojects/*` excludes all .wrap files, and `!subprojects/gst*` is
not enough because e.g. `macos-bison-binary` is still ignored. Instead
ignore only directories except those we include in our git repository.
