[PATCH 2/2] wineboot: Shrink the prefix path string if it's too long.

[Aida Jonikienė]

From: Aida Jonikienė

This change caps the prefix path to 15 characters from both the start and
end with a ellipsis in the middle if the prefix path string doesn't fit
in the dialog's test box (this is a hardcoded value).
