This will cause problems when programs are running while packages are
updated on disk. That program then tries to dlopen 18-0.so when there
is already 18-1.so installed. Relevant when the first oauth connection
is made way after startup.

This is trading one problem for another, but within-a-major ABI
changes should be much rarer than normal minor updates with
applications restarting only later.

Alternatively, there could be a dedicated SONAME for the plugin that
only changes when necessary, but perhaps the simple "18.so" solution
is good enough.
