[GITEA] admin: "Self Check" should only show for some db types

The "Self Check" menu essentially runs the collation check that is also
performed at startup, and displays the results. This is only a thing for
MariaDB/MySQL and MSSQL. As such, the menu item should only be available
for these database types.
