Dont write data attrs for cc lib rules
The data attributes for cc library rules is dropped by their starlark
macros, so serves no real purpose. Furthermore, this unused dependency
proves problematic for allowlist v2, as there are many cases at HEAD
where the corner-case "requires" dependency would otherwise mark a module
as unconvertible.
Fixes: 303307456
Test: New unit test
Test: Manual verification to unblock allowlist v2 `bp2build.sh` runs in
AOSP
