The convention on Unix is to use lib/5.1/mymodule.so,
lib/5.2/mymodule.so and lib/5.3/mymodule.so. Keeping the name as
mymodule.<extension> saves troubles with require() as you said, and
then it becomes only a matter of making LUA_CPATH (or LUA_CPATH_5_3
etc.) point to the right places (which is something you'll have to
deal with on Windows, anyway).

So in short, yeah, it's best to leave versioning to the directory name
and not the filename of the module.
