terminal.py: Fix Xfce on ubuntu/debian; some cleanup
* Xfce class was setting and passing wrong variable for ubuntu/debian. * Xfce class was using -e instead of -x for passing command. The former creates a shell escape nightmare * Clean up local and instance/class variables with same name but different usage. * Remove side-effect and directly return formatted command for clarity. (From OE-Core rev: b2ee5c5e34cdc3d65ca7b5da3486360a74d6c500) Signed-off-by: Jeffrey C Honig <jeffrey.honig@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
