CSP source *.x.y should not match host x.y

CSP source *.x.y should not match host x.y

This fixes a minor CSP bug where a source in a source list with a
wildcard was matching more liberally than it should have. It was
matching a source of the form *.x.y to host x.y when, in fact, it should
only be matching subdomains.

Any idea what happened to this one? Generally, it's bad practice to change the
meaning of enums, since data from different versions will mean different things,
but will be labeled with the latest histograms.xml change. But perhaps in this
case, the meaning was still the same and the wording was just made more precise?

No idea what happened here; this is just the result of running
update_use_counter_feature_enum.py.
