Upgrade jhbuild dependencies (#51)

Switch to new libwpe/wpebackend-fdo releases, upgrade
libdex/libpanel/etc.
Make sure to always attach tags to checkouts, to guarantee a certain
version is used, independant of the image build time (where possible).

This includes the PR #50, and needs to rebased, once it's merged to
main.
