perf annotate: Propagate perf_env__arch() error
The callers of symbol__annotate2() use symbol__strerror_disassemble() to
convert its failure returns into a human readable string, so
propagate error values from functions it calls, starting with
perf_env__arch() that when fails the right thing to do is to look at
'errno' to see why its possible call to uname() failed.
