bpftool: Add arguments for filtering in and filtering out probes

Add positional arguments "filter_in" and "filter_out" to the feature
command of bpftool. If "filter_in" is defined, bpftool is going to
perform and print only checks which match the given pattern. If
"filter_out" is defined, bpftool will not perform and print checks which
match the given pattern.

Syntax of the "bpftool feature" command after this change is:

  bpftool feature probe [COMPONENT] subsystem [SUBSYSTEM] [filter_in PATTERN] [filter_out PATTERN] [macros [prefix PREFIX]]
  COMPONENT := { kernel | dev NAME }
  SUBSYSTEM := { all | system-config | syscall-config | program-types | map-types | helpers | misc }
