certctl: don't fall over flat with relative DESTDIR

Up until now, all of our DESTDIR use has been with absolute paths. It turned
out that the cd in/out dance we do here breaks us down later on, as the
relative path no longer resolves.

Convert EXTENSIONS to an ERE that we'll use to grep ls -1 of the dir we're
inspecting, rather than cd'ing into it and globbing it up.

MFC after:	3 days
