BUILD: peers: adjust some printf format to silence cppcheck

In issue #1184, cppcheck complains about some inconsistent printf
formats. At least the one in peer_prepare_hellomsg() that uses "%u"
for the int "min_ver" is wrong. Let's force other types to make it
happy, though constants cannot cause trouble.
