dbus-broker: 16 -> 18

Also brings in a patch to fix up building against a musl libc that is
not in a released build yet.

This change cleans up a number of things about the build
 - Upstream no longer depends on glib
 - We dont ever runtime depend on reference dbus
 - Docs are disabled by default so we don't need to specify the option
 - There is no native tooling so we shouldn't need a native bbclass
 - No longer depend on gitsm since upstream provides release tarballs
