It was discovered that some titles rely on filesystem metadata to work properly. Currently, in master they either simply won't find their save files (for example Bolt) or will complain about the Wii system memory being corrupted (on first use or every time depending on the title). In order to even be able to keep track of file metadata, we first need to eliminate all direct accesses to the NAND and make all kinds of operations go through the filesystem code added in PR 6421. This commit starts the migration process by making SysConf use the new FS interface.
