cmd/dist: drop remaining conditions on default cgo tests
Currently, dist registers cmd/cgo/internal{test,testtls,testnocgo}
specially, so they're opted out of "go test std cmd". It has to
register these test packages to run in various non-default build
configurations, but at this point they can also run with the default
build configuration (and for test and testtls, we intentionally want
to test them in the default configuration; this is pointless but
harmless for testnocgo). Hence, this CL drops the special registration
of their default build configurations from registerCgoTests and lets
them be registered as part of registerStdTests.
