libctf: fix testsuite bugs revealed by -Wall
Most of these are harmless, but some of the type confusions and especially a missing ctf_strerror() on an error path were actual bugs that could have resulted in test failures crashing rather than printing an error message. libctf/ * testsuite/libctf-lookup/enumerator-iteration.c: Fix type confusion, signedness confusion and a missing ctf_errmsg(). * testsuite/libctf-regression/libctf-repeat-cu-main.c: Return 0 from the test function. * testsuite/libctf-regression/open-error-free.c: Fix signedness confusion. * testsuite/libctf-regression/zrewrite.c: Remove unused label.
