Improvements to asciidoctor build. (msys2#3350)

* Improvements to asciidoctor build.
1) Fix hardcoded pathes causing bug report ( https://github.com/Alexpux/MINGW-packages/issues/3338 )
2) Along similar lines, added .install files that fix the batch files to use DOS path references that should be valid.  This has to be done on the uer's system.
3) Add testing from the ruby gem.

* update QPDF to version 7.1.1 (msys2#3349)

* Redo the path fixups that are required for distribution.  *.bat files, drop path refs.  For the .sh scripts, may sure that they are not hard-coded to the installation dirs.  Just use something like /mingw64/bin/ruby and /mingw32/bin/ruby are used to that we calling the correct interpretter in an MSYS environment.
