Plex now provide a first-party musl Plex build that works without any
external dependencies whatsoever. It's built with LLVM with many
compiler and linker optimisations enabled:

Changes for this release include:
- Drop curl, OpenSSL and zlib; they're no longer required. libcurl and
libssl/libcrypto are provided by Plex anyway.
- Build `FROM spritsail/alpine` instead of `FROM debian` to ensure musl
compatibility with all compiled binaries. Use `FROM scratch` for the
resulting image. ld-musl is provided by Plex.
- Build busybox, su-exec and tini as they're no longer provided by the
base image.
- Build binaries/libraries with standard hardening flags, including the
popular -flto.

This should cover 95% of cases where we'd want to bump Plex, but
autonomously. If the build fails or the tests fail we'll know about it
and can manually investigate.

This allows running multiple builds of the same pipeline on one Docker
daemon, and also makes configuration simpler, as the argument is
implied if not provided.
