[OE-core] [PATCH] terminal.py: Allow devshell/menuconfig on recent gnome-terminal

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

Recent versions of gnome-terminal does not support non-UTF8 charset:
https://bugzilla.gnome.org/show_bug.cgi?id=732127 as a result, devshell and
menuconfig tasks silently hang  (error found on trace log of 'strace -f -v
-s 8192 -e write=2 bitbake -c devshell quilt-native': "Non UTF-8 locale
(ANSI_X3.4-1968) is not supported!"). As a workaround, clearing the LC_ALL
environment variable so it uses the locale. Once fixed on the gnome-terminal
project, this should be removed.

Tested on gnome-terminal versions:

       GNOME Terminal 3.4.1.1
       GNOME Terminal 3.14.2 (Default on Ubuntu 15.04)
