Bug#964772: gem2deb: should not install mkmf.log files

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
gem2deb was generating Debian packages that were not reproducible.

For example, ruby-enumerable-statistics was installing a mkmf.log file
that contained various absolute build paths, which will make the package
not reproducible.

I note that there is code already in gem2deb that attempts to not
install these (?), but it does not appear to be working. Patch
attached, although this is just a proof of concept and/or to
demonstrate the problem a little more.
