sudoers.d: Stops QT from using the MIT-SHM X11 Shared Memory Extension

Fedora now needs this sudoer rule.  Allows sudo to keep the `QT_X11_NO_MITSHM` ENV
variable which prevents MIT-SHM errors for Fedora and Debian when running a QT
application:

    `Defaults env_keep += "QT_X11_NO_MITSHM"`

A complementary commit has been made in gui-agent-linux:
