Subject: [PATCH] build: Exclude cscope and tags files from packaging

When building a Debian package, cscope and tags generated files are
accounted in the Debian packaging process, even causing some errors
under some circumstances (generating diff between "pristine" tar and
"patched sources").

Ignore these generated files for packaging related purposes.
