git-webkit setup crashes when the macOS keychain is locked

[Elliott Williams]

If your session does not have a keychain unlocked (e.g. you're connected via ssh), git-webkit setup crashes without an actionable message:

    Provide github.com username and access token to create and update pull requests
    Username: emw-apple
    Token: 
    Store username and token in system keyring for https://api.github.com? ([Yes]/No):

It should either run `security unlock` directly for you, or fail more gracefully.

There will still be trouble opening GitHub.com when on ssh, but one could take a token from their keychain on another computer.

Duping to https://bugs.webkit.org/show_bug.cgi?id=242647, which is effectively the same issue.
