Subject: [PATCH 2/3] multipass: build and install the flutter gui

This commit breaks down multipass into two intermediate packages,
`multipassd` and `multipass-gui`. These are then packaged up with
`symlinkJoin` to work around some intricacies in the
`buildFlutterApplication` process which would otherwise be difficult
to patch.

The multipass repo is setup upstream such that the flutter app would
be built as part of the regular cmake process, but that can't work
here due to the fetching of the flutter dependencies. The upstream
multipass project builds `libdart_ffi.so`, which is needed in the
LD_LIBRARY_PATH of the GUI. Building the two derivations seperately
enables that to be done relatively simply.
