WSL: refactored smb_share commands
WSL: refactored smb_share commands

- Using "ls /mnt" with WSL and "ls /cygdrive" with Babun instead of wmic.exe to list disks
- Using winsudo with Babun and sudowin with WSL
- Simplified SMB share remark to avoid escaping spaces with sudowin
- Using ${USERDOMAIN}\${USERNAME} in smb_share_create, otherwise the user does not have access to the share (recent changes in Windows?)
