perf probe: Use PARSE_OPT_EXCLUSIVE flag

The perf probe command has some exclusive options.  Use new PARSE_OPT_EXCLUSIVE
flag to simplify the code and show more compact usage.

  $ perf probe -l -a foo
    Error: switch `a' cannot be used with switch `l'

   usage: perf probe [<options>] 'PROBEDEF' ['PROBEDEF' ...]
      or: perf probe [<options>] --add 'PROBEDEF' [--add 'PROBEDEF' ...]
      or: perf probe [<options>] --del '[GROUP:]EVENT' ...
      or: perf probe --list
      or: perf probe [<options>] --line 'LINEDESC'
      or: perf probe [<options>] --vars 'PROBEPOINT'

      -a, --add <[EVENT=]FUNC[@SRC][+OFF|%return|:RL|;PT]|SRC:AL|SRC;PT [[NAME=]ARG ...]>
                            probe point definition, where
GROUP: Group name (optional)
EVENT: Event name
FUNC: Function name
OFF: Offset from function entry (in byte)
%return: Put the probe at function return
SRC: Source code path
RL: Relative line number from function entry.
AL: Absolute line number in file.
PT: Lazy expression of line code.
ARG: Probe argument (local variable name or
kprobe-tracer argument format.)

      -l, --list            list up current probe events
