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.
