ctfc: externalize ctf_dtd_lookup

Expose the function ctf_dtd_lookup, so that it can be used by the BPF
CO-RE machinery. The function is no longer static, and an extern
prototype is added in ctfc.h.

gcc/ChangeLog:

	* ctfc.c (ctf_dtd_lookup): Function is no longer static.
	* ctfc.h: Analogous change.
