tools lib traceevent: Check string is really printable
When libtraceevent parses format fields, it assumes that array of 1 byte
is string but it's not always true. The kvm_emulate_insn contains 15 u8
array of insn that contains (binary) instructions. Thus when it's
printed, it'll have broken output like below:
kvm_emulate_insn: [FAILED TO PARSE] rip=3238197797 csbase=0 len=2 \
insn=<89>P^]<B4>& flags=5 failed=0
With this patch:
kvm_emulate_insn: [FAILED TO PARSE] rip=3238197797 csbase=0 len=2 \
insn=ARRAY[89, 10, 5d, c3, 8d, b4, 26, 00, 00, 00, 00, 55, 89, e5, 3e] flags=5 failed=0
