Look for dynamic linker in /bin/less in integ test

[daniel-levin]

More Illumos fun! This change checks less for a dynamic linker as well. Formatting the array makes the change look larger than it is. Combined with #1158 we are now up to 27 passing integ tests on Illumos, up from just 9. As for why less? Well, it's a pager that's pretty pervasively installed, so why not make a last-ditch effort there?

It turns out that on Illumos, lots of coreutils are actually 32-bit binaries. I tracked this down to here. I printed the error returned by object - something about invalid headers. Sure enough - less is 64 bit and ls is 32 bit!
