Upgrade permissions on PermissionController version change

If the version of the permsision controller is different than what was
persisted then call the upgrade controller defined in the permission
controller.

Exempt-From-Owner-Approval: Got verbal approval from an OWNER

Bug: 148595539
Test: Manual; verify the version is persisted in runtime-permissions.xml
              verify the upgrade is run when changing the version number
	      move runtime-permissions.xml to old location, verify works
