media-sound/deadbeef-1.8.0 fails to compile with musl [patch]

[stefson]

the build fails, as it cannot find queue.h file from glibc. musl doesn't have this fully implemented, and to fix this typ of errors there's a standalone of the header available from the gentoo tree. The patch pulls this in on condition of musl being installed.
