Adjust visibility rules prior to migration.

system/timezone/geolocation is moving to packages/modules/GeoTZ project
and this visibility change allows for geo_lookup to utilize the
testdata.  Soong does not enforce the visibility paths for existence, so
this change is safe and needed prior to migration.
