Rename snmptrapd command line program to navtrapd

[lunkwill42]

Fixes #2882

This really just renames the installed "binary", it does not change the internal module names or references otherwise.

Why not also rename the nav.bin.snmptrapd file itself? Partly renaming seems like something that could be confusing

Simply because it's more work (than a simple bugfix) :)

Merge this now, do the internal rename(s) in a later patch-release so that we can get feedback on the new externally visible name as soon as possible.
