Single-file builds incur a performance cost. Mainly because the runtime
must extract the contents of the C# application to a temp directory in
order for it to run. In a Docker container, single-file offers no
tangible benefit because the user isn't interacting directly with those
files.
To gain some performance improvement, single-file is disabled for MUSL
builds. Furthermore, the docker image is reconfigured to place the
Recyclarr binary files in a different directory. Previously, as a
single-file binary, it was placed in the container at `/usr/local/bin`,
but now that it is a multiple-file application, it now lives in
`/app/recyclarr`.
