Test for qpdf existence only if it matters

Packages with a HTML vignette (but no PDF vignette) give warnings with
R CMD check --as-cran on a system without qpdf. I think the warning
originates here [1], due to a premature check for the existence of qpdf
[2]. Setting R_QPDF=true (as in /bin/true) helped, but perhaps it's
possible to check qpdf existence only when it matters.

Example build: https://ci.appveyor.com/project/ropenscilabs/monkeylearn

I have attached a patch (untested, based on r71220) that could serve as a starting
point. Thanks.
