tools: bpftool: fix -Wmissing declaration warnings

Browse source

[ Upstream commit c101189bc9 ]

Help compiler check arguments for several utility functions used to
print items to the console by adding the "printf" attribute when
declaring those functions.

Also, declare as "static" two functions that are only used in prog.c.

All of them discovered by compiling bpftool with
-Wmissing-format-attribute -Wmissing-declarations.
