gnu: MariaDB: Disable the TokuDB plugin.

Fixes <https://bugs.gnu.org/35521>.
Reported by Mark H Weaver <mhw@netris.org>.

* gnu/packages/databases.scm (mariadb)[arguments]: Pass "-DTOKUDB_OK" in
<#:configure-flags>.  Enable the "innodb_fts.crash_recovery" test, which
likely failed because of the high I/O load induced by TokuDB.
[inputs]: Remove SNAPPY.
