[electrum] build: remove deprecated apt-key for winehq key

Summary:
apt-key is deprecated and keys should be specified per source instead of
for all sources.

This is a backport of [[Electron-Cash#2820 | electroncash#2820]]

Also fix the build by bumping `windbind` to a version that supports the current dependency packages available in the ubuntu repo (`samba-common`...)

Test Plan: build the windows release `contrib/build-wine/build.sh`, and test the executables
