sandbox: do not run xmodmap in a new X session

xmodmap causes Xephyr X server to reset itself when it's run before wm
and even right after wm. It causes termination of the server as we use
-terminate. The -terminate option seems be important enough in order not
to left running the server when the last client connection is closed.

This patch drops the execution of xmodmap from .sandboxrc until there's
a better solution.
