ardour: fix default plugin search paths

Browse Source 
Since NixOS has different paths for plugins than what Ardour assumes by
default, we should patch these defaults to be correct on NixOS.

While Ardour does indeed respect environment variables such as VST_PATH,
it only does so if a profile configuration was never created. Using this
patch the correct paths are also picked, when the user clicks the "Reset
to Default" button in the path editor.

Subject: [PATCH] add NixOS plugin paths as default search paths
Since NixOS uses unusual paths, we should tell Ardour about this. During
first launch, Ardour does indeed check for environmentals but not when
you press the "Reset to Defaults" button in the Settings menu. This
path fixes this by including NixOS paths in the defaults.
