libctf: Sanitize error types for PR 30836
Made sure there is no implicit conversion between signed and unsigned
return value for functions setting the ctf_errno value.
An example of the problem is that in ctf_member_next, the "offset" value
is either 0L or (ctf_id_t)-1L, but it should have been 0L or -1L.
The issue was discovered while building a 64 bit ld binary to be
executed on the Windows platform.
Example object file that demonstrates the issue is attached in the PR.
libctf/
Affected functions adjusted.
