Just run exactly the same set of software you had on a CentOS 6.7 host just to be sure…
The output I have is
"…

The SECOND run of the ps_tokudb_admin script (you need to run it twice and restart the service between) you should see these entries.
Checking TokuBackup plugin status…
INFO: TokuBackup plugin is installed.
Checking if Percona Server is running with libHotBackup.so preloaded…
INFO: Percona Server is running with libHotBackup.so preloaded.
If you do not then that will be an indication of the problem.
And if you DO NOT have the preload in the my.cnf (see last entry of the first run) the plugin doesn’t load either.
