MDEV-6543 Crash if enable 'federatedx' when 'federated' plugin already enabled, and vice-versa

Browse Source 
INSTALL SONAME ignores attempts to load the same plugin twice, it's not an error
(because one can load one plugin by name and then install soname for the rest).
But Federated and FederatedX are different plugins, despite having the same name.

Now plugin_add() only considers two plugins identical if their names are the same
string (compared as pointers). Otherwise it reports an error.,
