Return and absolut path in DRIVE_FindDriveRoot

[Uwe Bonnes]

Hallo,

some application (xilinx webpack) dind't find it's initialisation file when
started in the debugger ("winedbg bin/nt/webpack.exe" versus "wine
bin/nt/exepack" started in "l:/xilinx"). As trap there is also a directory
"l:/xilinx/xilinx". The starting process (wine or winedbg) set the current
working directory to l: and when winedbg started the user process,
DRIVE_Chdir in DIR_Init set the current directory to "l:/xilinx/xilinx".
This was caused by DRIVE_FindDriveRoot not returning an absolute path.

Changelog:
	files/drive.c: DRIVE_FindDriveRoot
	Return and absolut path, if any

Bye
