BUILD/MINOR: peers: shut up a build warning introduced during last cleanup

A new warning appears when building at -O0 since commit 3f0fb9df6 ("MINOR:
peers: move "hello" message treatment code to reduce the size of the I/O
handler."), it is related to the fact that proto_len is initialized from
strlen() which is not a constant. Let's replace it with sizeof-1 instead
and also mark the variable as static since it's useless outside of the file.
