qt5connectivity: propagate bluez-utils dependencies

qt5connectivity selects the bluez-utils package but the dependencies are
not fully propagated so someone could do a static build, then select the
qt5connectivity package causing bluez-utils being auto-selected, which
is disabled for static builds, and then obtain a build failure like this
one:

checking for dlopen in -ldl... no
configure: error: dynamic linking loader is required
