[archive] Check unrar with commands array

“unrar-free returns the error code 1 when run without arguments, thus
failing the presence check.” as reported at sorin-ionescu/prezto#1383

Reformat code and use one-liners instead of if/then/fi. And we don’t
need to separate local definitions from assignments anymore starting
from zsh 5.2.
