`rc.archlinux.asterisk`, which explicitly requests bash in its
shebang, uses the following command syntax:
${DAEMON} -rx "core stop now" > /dev/null 2&>1
The intent of which is to execute:
${DAEMON} -rx "core stop now"
While sending both stdout and stderr to `/dev/null`. Unfortunately,
because the `&` is in the wrong place, bash is interpreting the `2` as
just an additional argument to the `$DAEMON` command and not as a file
descriptor and proceeds to use the bashism `&>` to send stderr and
stdout to a file named `1`.
So we clean it up and just use bash's shortcut syntax.
Issue raised and a fix suggested (but not used) by peutch on GitHub¹.
