Fix incorrect invocation of Perl system builtin

It doesn't default to $_, but this code apparently assumes it does.

This doesn't seem to actually affect anything, because all the units I've
encountered have only the "pick" pseudo-command in the actions of their
"?MAKE:" sections. But I think it's worth fixing nonetheless.
