perf annotate: Fix warning message on a missing vmlinux

When perf annotate runs with no vmlinux file it cannot annotate kernel
symbols because the kallsyms only provides symbol addresses.  So it
recommends to run perf buildid-cache to install proper vmlinux image.

But running perf buildid-cache -av vmlinux as the message gives me a
following error:

  $ perf buildid-cache -av /home/namhyung/build/kernel/vmlinux
  Couldn't add v: No such file or directory

Since the -a option receives a parameter, 'v' should not be after the
option.

In addition -a option is not work for this case since the build-id cache
already has a kallsyms with same build-id so it'll fail with EEXIST.
Use recently added -u (--update) option for it.
