[PATCH] libtracefs .gitignore: only ignore patches/ at top level

The Debian packaging of libtracefs might carry patches in
`debian/patches/` but the `.gitignore` file will ignore this directory.

So tighten the `.gitignore` to only ignore a `patches` directory in the
top-level of the git repository.
