Fix D-Bus build without ctrl_iface

Commit 7de5688d682d4a96a4ce1f7959428a0112d4b75f started using
wpa_supplicant_ctrl_iface_ctrl_rsp_handle() from the D-Bus code, but
left this function in ctrl_iface.c that is included conditionally. Fix
this by moving the common function into wpa_supplicant.c so that it can
be included for builds that include only either ctrl_iface or D-Bus.
