vendor/cmd/go/internal/modfetch: update gopkg.in requirements in TestConvertLegacyConfig

Support for major-version parsing for gopkg.in dependencies was
improved in CL 107658, but TestConvertLegacyConfig was apparently not
updated to reflect that.

Updates golang/go#25501.

Before:

--- FAIL: TestConvertLegacyConfig (32.51s)
    --- FAIL: TestConvertLegacyConfig/github.com_docker_distribution_v0.0.0-20150410205453-85de3967aa93 (0.00s)
        convert_test.go:102: golden:23: invalid module: gopkg.in/yaml.v2 should be v2, not v0 (v0.0.0-20150116202057-bef53efd0c76)

After:

--- PASS: TestConvertLegacyConfig (40.00s)
    --- PASS: TestConvertLegacyConfig/github.com_docker_distribution_v0.0.0-20150410205453-85de3967aa93 (40.00s)
