fix(cli): remove set -e from bin/doom{,script}

This killed the script prematurely (without displaying the error) if
Emacs failed to execute. In versions prior to bash 4, set -e would not
terminate the script if a non-zero exit code occurred within a subshell,
but it will in bash 4+.

In any case, we don't need this fallback to begin with. The script
handles its errors sufficiently otherwise.
