package/mariadb: fix sub-option indentation

The Config.in comment is between the main BR2_PACKAGE_MARIADB option
and its sub-options, causing the sub-options to not appear as nicely
indented in menuconfig.

Before:

[ ] mariadb
[ ] mariadb server
  [ ] mariadb embedded server

After:

[ ] mariadb
  [ ] mariadb server
    [ ] mariadb embedded server

which is what we want.
