user/qt5: Bump to 5.12.6 LTS

This updates Qt 5 to the latest LTS release available.  Notable changes:

* The infamous clipboard bug (upstream QTBUG-65145; Gerrit 254187) is fixed!

* Qt Declarative's "V4 JIT" is disabled globally on pmmx.  It is no longer
  (easily) possible to turn off the JIT selectively based on CPU capability.

* Qt Script builds correctly on GCC 8 now.

This does not include:

* Build testing of Qt Multimedia (yet); this depends on the time64-isation
  of the alsa-lib package (at least).

* Build testing of Qt Speech (yet); speech-dispatcher also deps on alsa-lib
  indirectly.

* Qt WebKit 5.212.  This will be committed later.
