[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 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
