connman: update musl incompatibility reason

connman no longer triggers a conflict of userspace and kernel headers since
commit 69ced96355 (musl: workaround kernel if_ether.h header conflict). The
real blocker for musl build (besides a few missing includes here and there)
is the missing res_ninit() implementation. Update the comment accordingly.
