Workaround perldtrace.h dependency problem
Enable "iso" by default.

This makes the package more useful for users of binary packages, who
can then burn a bootable memtest CD, and only costs 1.8 MB without
adding any run-time dependencies.  Source users get a dependency on
cdrtools, but that's likely already installed, and the option can
easily be turned off in that case (unlike binary package users, who
can't change options).
