[lttng-dev] [PATCH babeltrace] Fix: Added a null pointer check to bt_ctf_field_name.

[Jérémie Galarneau]

This function is called indirectly when calling __repr__ (print) in the python
bindings on the definition object returned by the get_top_level_scope method
thus resulting in a segmentation fault when the name attribute is not set.

Fixes #373
