perf test vmlinux: Clarify which -v lines are errors or warning
When the 'perf test -v vmlinux' test fails, it is not clear which of the
lines are errors or warnings, clarify that adding ERR/WARN prefixes:
# perf test -F -v 1
1: vmlinux symtab matches kallsyms :
--- start ---
Looking at the vmlinux_path (8 entries long)
Using /lib/modules/4.8.0-rc4+/build/vmlinux for symbols
