Change .gvfsCache folder to .vfsforgitCache

[chrisd8088]

The GVFS provider, by default, creates a ~/.gvfsCache folder during cloning, or a different location may be specified with --local-cache-path. As with #9, we should change the default name of this folder to .vfsforgitCache, at least on Linux.

See also microsoft#987 and microsoft#72.

Is it possible that a subdirectory of the XDG cache directory could be used for this purpose? Normally that would be $HOME/.cache if not specified in $XDG_CACHE_DIR. That makes it easier to find and clean up if disk space is tight.

Any idea why we do it this way on POSIX? On Windows we use the directory relative to the enlistment root.

I'm not sure why the Mac version, by default, seems to use ~/.gvfsCache ... but as for the XDG suggestion, I do like that, and it reminds me of my own issue over in microsoft/dotnet#880!
