[git commit] Makefile: fix cscope target

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=6c19d35f689c911b83073ab1faeffb8040c4b3d9
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

This target doesn't work with current directory layout. Just make cscope
index all .c and .h files.

While we're at it: add cscope output files to .gitignore.
