tests: Increase timeout in ap_bss_config_file for CTRL-EVENT-TERMINATING

If the kernel is built with CONFIG_DEBUG_KOBJECT_RELEASE=y, the hostapd
termination event for the wlan3 interface may be delayed beyond the
previous five second timeout. This could result in the test case failing
and the following test case failing as well due to the separate hostapd
process being still in the process of cleaning up.

Fix this by increasing the timeout to avoid forcing test termination in
such cases.
