Do not accept 'unknown' as a GL username
There are a few entries in owners.yaml where the gluser
field value is
unknown
. Presumably this is to indicate that we don't know this
person's GL username (why not???). But 'unknown' is a valid GL username
in use by someone unrelated to RH.
Fix this by setting the gluser value to 'null' in instances where it is not known and remove the parser check for null values.
