dpkg: runtime fixes for perl and shasums
dpkg: runtime fixes for perl and shasums

The whole show here is moving to libexec. The Perl problem we had
several versions ago and patched turns out to exist still.

We previously put in a fairly dirty patch for this, essentially
hacking out that element from the configure script. Given the continuing
problem I've just dumped everything in libexec here and env scripted it.

The env script is way less likely to break long-term than the dirty
patch we were using prior to the last release. My testing passed fine
for the last version bump, but evidently not every element of dpkg
calls for the Perl elements at run-time.

I also fixed a couple of rogue quotation marks on one of the inreplaces.
