ctfc: Free CTF container elements in ctfc_delete_container ()

Free up the memory held by hash tables containing CTF types and CTF variables
at the earliest.  This can be done in ctfc_delete_container () as CTF debug
informtion has already been emitted.

gcc/ChangeLog:

	* ctfc.c (ctfc_delete_container): Free hash table contents.
