ci: don't run unnecessary integration tests

Passing TEST_NAME to the integration test runner just passes that value
verbatim to go test. The value in go test is a regular expression though
, so if we have a test whose name is a prefix of another test,
both will be run.

We were running the FIPS test alongside the default test every time
because of this.
