libctf: lookup_by_name: do not return success for nonexistent pointer types
The recent work allowing lookups of pointers in child dicts when the
pointed-to type is in the parent dict broke the case where a pointer
type that does not exist at all is looked up: we mistakenly return the
pointed-to type, which is likely not a pointer at all. This causes
considerable confusion.
Fixed, with a new testcase.

* ctf-lookup.c (ctf_lookup_by_name_internal): Do not return the
base type if looking up a nonexistent pointer type.
* testsuite/libctf-regression/pptrtab*: Test it.
