We don't need to check the options twice, since it is the same check
both times. Instead, merge the conditionals.

As far as I can tell, the only reason the checks for:

- PACMAN_OPTS and
- whether to use sudo

were ever separated is due to the historic existence of --asroot, since
the second check included a check for (( ! ASROOT )) until it was
cleaned up in commit 61ba5c96
