Than McIntosh 956f8a67dd internal/coverage/cfile: harden the coverage snapshot test 
The existing testpoint TestCoverageSnapshot will fail if we happen to
be selecting a set of packages for inclusion in the profile that don't
include internal/coverage/cfile. Example:

 $ cd `go env GOROOT`
 $ cd src/internal/coverage
 $ go test -coverpkg=internal/coverage/decodecounter ./...
 ...
  --- FAIL: TestCoverageSnapshot (0.00s)
      ts_test.go:102: 0.276074 0.276074
      ts_test.go:104: erroneous snapshots, C1 >= C2 = true C1=0.276074 C2=0.276074

To ensure that this doesn't happen, extract the test in question out
into a separate file with a special build tag, and then have the
original testpoint do a "go test -cover -tags ... " run to make sure
that for that specific test run the cfile package is instrumented.

Fixes #67951.
