Subject: [PATCH] nixos/home-assistant: fix symlinking multi-manifest custom
 components

frenck/spook includes a second manifest for an integration. The current
copyCustomComponents script assumed that only one component directory
will be found, which in this case resulted in a malformed symlink
destination:
