Remove REQUIREDBY usage from libalpm

Instead of using the often-busted REQUIREDBY entries in the pacman database,
compute them each time they are required. This should help many things:

1. Simplify the codebase
2. Prevent future database corruption
3. Ensure when we do use requiredby, it is always correct
4. Shrink the pmpkg_t memory overhead
