Upgrade glob to v7.1.1

Summary:
> Explain the **motivation** for making this change. What existing problem does the pull request solve?

Of the three dependencies I have that rely on `glob`, react-native is the only one not on 7.x. If react-native can upgrade, then npm can deduplicate the glob dependency.

```console
$ npm ls glob
├─┬ eslint@3.13.1
│ └── glob@7.1.1
├─┬ jest@18.1.0
│ └─┬ jest-cli@18.1.0
│   └─┬ istanbul-api@1.1.0
│     ├─┬ fileset@2.0.3
│     │ └── glob@7.1.1
│     ├─┬ istanbul-lib-report@1.0.0-alpha.3
│     │ └─┬ rimraf@2.5.4
│     │   └── glob@7.1.1
│     └─┬ istanbul-lib-source-maps@1.1.0
│       └─┬ rimraf@2.5.4
│         └── glob@7.1.1
└─┬ react-native@0.39.2
  ├── glob@5.0.15
  └─┬ rimraf@2.5.4
    └── glob@7.1.1
```
