Nick Alexander f47a4b6764 Bug 1691951 - Make Windows install not register "ftp" protocol handler. r=application-update-reviewers,bytesized
For all channels, this commit:

1. stops registering the ftp protocol handler at install time;
2. actively unregisters the ftp protocol handler at postupdate time;
3. stops unregistering the ftp protocol handler at uninstall time.

The rationale for 3) is that by the time a `helper.exe` with this
change is in place, the `postupdate` step has already run and
unregistered the ftp protocol handler.
