perf annotate: Own objdump_path and disassembler_style strings
Make struct annotation_options own the strings objdump_path and
disassembler_style, freeing them on exit. Add missing strdup for
disassembler_style when read from a config file.
Committer notes:
Converted free(obj->member) to zfree(&obj->member) in
annotation_options__exit()
