perf probe: Allow to use filter on --del command

This makes perf-probe --del option to accept filter rules
not only simple glob pattern. This simplifies the code and
improve the flexibility.

E.g. if we remove 2 different pattern events, we need 2
     -d options.
  ----
  # ./perf probe -d vfs\* -d malloc
  Removed event: probe_libc:malloc
  Removed event: probe:vfs_read
  ----

  This allows you to joint the 2 patterns with '|'.

  ----
  # ./perf probe -d 'vfs*|malloc'
  Removed event: probe:vfs_read
  Removed event: probe_libc:malloc
