home: gnupg: Start ‘gnupg-agent’ with ‘--deprecated-supervised’.

* gnu/home/services/gnupg.scm (home-gpg-agent-shepherd-services)
[start]: Use `--deprecated-supervised` flag.

As of gnupg@2.5.20, the `--supervised` flag (systemd-style activation)
is deprecated. Using the `--deprecated-supervised` flag restores
previous behaviour, but extra investigation is required to migrate this
service to use the supported gpg-agent flags. See #10751 for an early
attempt.

Fixes: #10660
