bug#38544: gparted segfaults

[Ricardo Wurmus]

This segfaults:

    sudo /gnu/store/yzxyxnxja4y1riwh3mrqrvb7h4vhxlqb-gparted-1.0.0/bin/gparted

This does not segfault:

    sudo -E 
/gnu/store/yzxyxnxja4y1riwh3mrqrvb7h4vhxlqb-gparted-1.0.0/bin/gparted

The problem here is that when run as root but without the environment of
the current user gparted fails to find the image loader modules.
