perf probe: Accept filter argument for --funcs

Browse source

This allows the user to pass the filter pattern directly to the --funcs
option as below:

  ----
  # ./perf probe -F *kmalloc
  __kmalloc
  devm_kmalloc
  mempool_kmalloc
  sg_kmalloc
  sock_kmalloc
  ----

We previously needed to use the --filter option for that.
