package/pulseview: fix build with recent Qt versions

Browse Source 
This commit backports an upstream commit to fix the build of pulseview
with recent Qt versions.

Note that pulseview has a 0.4.2 version (newer than our 0.4.1) but it
doesn't have the fix we need. And 0.4.2 now requires additional Qt
translation tools, so the update to 0.4.2 is anyway not
straightforward.

Fixes:
