Add test option for specifying hardcoded BSS Load element

Browse source 
The new bss_load_test parameter can be used to configure hostapd to
advertise a fixed BSS Load element in Beacon and Probe Response frames
for testing purposes. This functionality is disabled in the build by
default and can be enabled with CONFIG_TESTING_OPTIONS=y.
