realpath: Handle Win32 and NT long path prefixes
So far drive letter paths have been handled special since path_conv
leaves the incoming path untouched except for converting backslashes
to forward slashes. However, if the incoming path starts with a
long path prefix, the same problem occurs. Therefore handle all
paths starting with a backslahs the same way.
