  Fix duplicate symbol entries in Symtab:everyFunction

A function should only be added to everyFunction if it was not already
in funcsByOffset or if it lives in a different code region from the
function found with the same offset.

This was introduced by https://github.com/dyninst/dyninst/pull/1534.
