Return if the GPG key described by the given keyid and timestamp are
installed in the rpmdb.
The keyid and timestamp should both be passed as integers.
The ts is an rpm transaction set object
Return values:
- -1 key is not installed
- 0 key with matching ID and timestamp is installed
- 1 key with matching ID is installed but has an older timestamp
- 2 key with matching ID is installed but has a newer timestamp
No effort is made to handle duplicates. The first matching keyid is used to
calculate the return result.
