Fix problems in CTF handling code exposed by the Coverity static analysis tool.
readelf * readelf.c (parse_args): Silence potential warnings about a
memory resource leak when allocating space for ctf option values.
(dump_section_as_ctf): Fix typo checking dump_ctf_strtab_name
variable.
libctf * ctf-archive.c (ctf_arc_write): Avoid calling close twice on the
same file descriptor.
