Fix build after copy of ContactsCommon dirs to Contacts

* Remove all references to the GoogleContactsCommon and
  ContactsCommon dirs
* Rename the aosp_contacts_dir variable to just contacts_dir
* Move contactsbind and commonbind to src-bind so that they
  can be excluded from the GoogleContacts build
