Win-gpg-agent

As far as I could see "Under Windows use LOCAL_APPDATA for the socket directory. [5537]" not only changed directory location but also introduced new way to look for home directories (at least under Windows). Because of that scoop "persist" home directory which is linked became unavailable to gpg-agent resulting in error on startup. Changing configuration to use non-linked location by default.

Move to go1.17

Win32-OpenSSH does not know how to redirect unix sockets (yet?), so we need actual TCP port to be able to RemoteForward gpg-agent with windows native ssh.

Adding autogenerated manifest to the release - this way scoop will be able to support latest release instantly

Switching to zip

Small code cleanup and next go version
