pv-wrap: Don't enable snapd workarounds by default

• pv-wrap: Don't enable snapd workarounds by default

  Since snapd 2.62, we do not need any special workarounds, and since https://github.com/canonical/steam-snap/pull/367 Canonical's Steam snap app has required snapd 2.62. This change is in the stable channel as of 2024-04-25, which means that the Steam snap app will refuse to install onto systems with an older snapd until the snapd has been upgraded.

  For now, disable the workarounds by default but keep them implemented. After we have a beta -> stable cycle without incident, we can delete their implementations.
