The current test attempts to instantiate two spicy::SSH_1 protocol
analyzers in the .evt file. The intention likely was to use two
distinct protocol analyzer both trying to replace the builtin SSH
analyzer.
Coincidentally, fixing this happens to workaround TSAN errors tickled
by the FatalError() call while loading the .hlto with two identically
named analyzers.

I was tempted to replace FatalError() with Error() and rely on
zeek-setup.cc's early exiting on any reporter errors, but this
seems easier for now.
Relates to #3865.
We now reject EVT files that attempt to replace the same built-in
analyzer multiple times as doing so would be ill-defined and not very
intuitive in what exactly it means.
Closes#3783.
