hostapd does not actually transmit the Beacon frames. It provides a
frame template to the kernel (driver or 802.11 stack) and the actual
transmission is coordinated by the WLAN driver (and/or firmware).

With some drivers (e.g., most drivers using mac80211), hostapd takes
care of Probe Request frame processing and sending of the Probe Response
frames (which have similar information to the Beacon frames).
