Add z_SUITE to validate loaded code
If we want to have test cases that run eprof, we must make sure that
there are no modules loaded that don't have a working module_info/1
function, since eprof calls module_info(functions) to retrieve the
list of functions in the module. Some test cases load modules compiled
from Core Erlang that don't have any module_info/1 functions, so
we will need make sure that all such modules have been unloaded.
Add z_SUITE:loaded/1 to run after all other test cases to verify that
all modules that the code server consider loaded are indeed loaded and
all have working module_info/0,1 functions.
