perf annotate: Fix the signedness of failure returns

Callers of symbol__annotate() expect a errno value or some other
extended error value range in symbol__strerror_disassemble() to
convert to a proper error string, fix it when propagating a failure to
find the arch specific annotation routines via arch__find(arch_name).
