geography/qgis: Update to 3.16.4

This is an update from the 3.10 LTR to the newly-designated 3.16 LTR.
Besides hand-re-applying patches, and believing the new PLIST, the
only change is a new dependency on protobuf.

Upstream NEWS

# 3.16

This release brings a wealth of new options for 3D mapping, mesh
generation from other data types, additional spatial analysis tools,
symbology and user interface enhancements to name but a few! A host of
tools have been incorporated into the ever-expanding processing
framework, and the QGIS browser now supports advanced database
interaction functionality that was previously reserved for the DB
Manager plugin.

advances in mdal / mesh support, native support for temporal data in
WMS-T, PG Raster, vector providers, and mesh layers. Users focussed on
cartography and digitising haven窶冲 been left out either, with many new
options for you!
