[bug#49502] [PATCH] gnu: qpdfview: Use qt-build-system.

[Timotej Lazar <timotej.lazar@araneo.si>]

This fixes compilation after the recent reorganization of qt-build-system. As
a side effect, specifying Qt plugins with environment variables now works.

* gnu/packages/pdf.scm (qpdfview): Use qt-build-system.
[arguments]: Drop #:modules and #:imported-modules, and the 'qt-wrap
phase. Specify that there are no tests.
