kernel32: Implement GetVolumePathName.

Description:
    This patch implements GetVolumePathName by using the full folder
path and working backward until stat() returns a different device.  I
encountered issues with having this function unimplemented after
installing Portal 2 and attempting to launch the game for the first
time (the "completing installation" failed).  After looking into the
issue, I found that steam has been updated in such a way that the
"first run installation" calls CreateFile using FILE_OPEN_BY_FILE_ID
(lookup by inode).  Since my steam installation is on a different
filesystem than my root partition, this meant that steam passed the
wrong root search path to CreateFile and resulted in steam being
unable to locate its files.
