bpftool: feature probing, change default action

Browse source 
When 'bpftool feature' is executed it shows incorrect help string.

test# bpftool feature
Usage: bpftool bpftool probe [COMPONENT] [macros [prefix PREFIX]]
       bpftool bpftool help

       COMPONENT := { kernel | dev NAME }

Instead of fixing the help text by tweaking argv[] indices, this
patch changes the default action to 'probe'. It makes the behavior
consistent with other subcommands, where first subcommand without
extra parameter results in 'show' action.
