[PATCH 04/17] corpus: Support adding translation units with empty path

[dodji@redhat.com]

From: Dodji Seketeli <dodji@redhat.com>

The CTF front-end produces an artificial translation unit with an
empty path for all the types in a given ABI corpus.  Adding such a
translation unit to its corpus is conditioned on it having a non-empty
path.  Oops.  Fixed thus.

	* src/abg-corpus.cc (corpus::add): Do not require that the path of
	the translation unit be non-empty.
