Fix bug #7982: LyX does not work if working directory a hard disk drive like D:\

In this case, the working dir has already a slash at the end.
Appending another one would result in a path ending with a double slash,
which has a special meaning when used in TEXINPUTS (all subdirs would
be recursively scanned). So, avoid doing that.
