TestBenchmarkBytes fails on Windows

[rillig]

To reproduce:

• git co 788fd78
• go test

Output:

FAIL: benchmark_test.go:62: BenchmarkS.TestBenchmarkBytes

benchmark_test.go:74:
    c.Assert(output.value, Matches, expected)
... value string = "PASS: check_test.go:151: FixtureHelper.Benchmark2\t      10\t   1597640 ns/op\t   0.64 MB/s\n"
... regex string = "PASS: check_test\\.go:[0-9]+: FixtureHelper\\.Benchmark2\t\\s+[0-9]+\t\\s+[0-9]+ ns/op\t\\s+ *[1-9]\\.[0-9]{2} MB/s\n"

The test fails because 0.64 MB/s doesn't match [1-9]\.\d+.

This looks to be fixed by 10cb982 (which updates the CI to run the test suite on Windows), which makes the suggested change to the regexp.
