[OE-core] [PATCH] lib/oe/terminal.py: fix gnome-terminal start behavior

[Trevor Gamblin]

[Bugzilla Bug 13201] -- https://bugzilla.yoctoproject.org/show_bug.cgi?id=13201

Newer versions of gnome-terminal (3.32.0 and up) are not starting
as expected for commands e.g. "bitbake -c devshell zlib". This
manifests as the instance appearing as a new tab rather than a
new window. Fix this (and maintain new window preferred behavior)
by changing the "-x" option to "--" as per the warning message,
avoiding deprecated options:

    # Option “--command” is deprecated and might be removed in a later version of gnome-terminal.
    # Use “-- ” to terminate the options and put the command line to execute after it.
