mingw: support UNC as file://server/share/repo

Windows users might think that the common file:/// protocol also works for network shares. This patch makes it so.

Extend the parser to accept file://server/share/repo in the way that Windows users expect it to be parsed who are used to referring to file shares by UNC paths of the form \\server\share\folder.

[jes: tightened check to avoid handling file://C:/some/path as a UNC path.]

This closes https://github.com/git-for-windows/git/issues/1264.
