Adds an option to start wireless access point directly from RetroArch
settings menu (Services submenu). This wireless access point can be then
used for local netplay. If not defined in a specific config file
(LAKKA_LOCALAP_PATH), the arbitrary values for SSID/PassKey of the
created access point are LakkaAccessPoint/RetroArch. The menu/option is
added only in case when compiling with HAVE_LAKKA.
