i965: Make INTEL_DEBUG=state ignore state flags with a count of 1.

There are too many state flags to fit in one terminal screen, even with
a very tall terminal.  Everything is flagged once, so a value of 1 means
that it hasn't ever happened again, and thus isn't terribly interesting.

Skipping those makes it easier to see the interesting values.
