GCC was more picky about prototypes for inlines being required.
The generate_listener.py script used incorrect printf formats and
was casting %f params to float, but printf casts all %f params to
double per the spec.

The posix build would complain that toipc_listener.cpp did not exist
and there was no rule to create it.
The required rule was added to src/systemcmds/topic_listener/module.mk
The script generate_listener.py is run from the Build tree and needs to
access $(PX4_BASE)/msgs so $(PX4_BASE) is now passed as an argument to
generate_listener.py
