lisa.trace: Try building the kmod for optional events

FEATURE

Optional events are currently ignored if the kernel does not provide
them. Instead, attempt to build the module if the kernel does not
provide a missing event. This is especially important as the user's
events from the user-provided FtraceConf are treated as optional.
