Use distinct GateKeeper userids when running a GSI.
GateKeeper uses userids to key authentication data. This poses a problem
for GSIs, since both the GSI and the host image will be storing separate
authentication data for the same userids.
To account for this, we add a large offset (1000000) to GSI userids
before handing them off to the GateKeeper HAL. Note that
SyntheticPasswordManager uses a similar trick to store Weaver data in
GateKeeper (when a Weaver HAL is not available).
