SERVER-13563 Add old package names to RPM Provides and Conflicts

This is two changes for every package and sub-package of both
community and enterprise:
1) Add the equivalent old package name to each package's Provides
field
2) Add the equivalent old package name to each apckage's Conflicts
field.

Tested scenarios that should work:
* Upgrading from 2.4.10 (Vs. uninstalling then installing)
* Installing sub-packages with new name
* Installing sub-packages with old name
* Installing metapackage with new name
* Installing metapackage with old name
* Installing old versions of packages using new --exclude
  mongodb-org,mongodb-org-server syntax
* Installing third party package that depends on old package name
  (new packages were automatically installed)
