Pkgsrc WIP package to update Spotifyd to 0.4.2

[atomicules <base%atomicules.co.uk@localhost>]

I've added a WIP package to update spotifyd from 0.4.1 to 0.4.2. The
upstream changes pull in the same librespot fixes that ncspot had to
pull in recently. I.e. fixes playing again.

Built and tested on NetBSD 10.1 amd64.

If someone could pull that across to main I would appreciate it.

Thanks.
