ubifs: Implement RENAME_EXCHANGE
Adds RENAME_EXCHANGE to UBIFS, the operation itself is completely disjunct from a regular rename() that's why we dispatch very early in ubifs_reaname(). RENAME_EXCHANGE used by the renameat2() system call allows the caller to exchange two paths atomically. Both paths have to exist and have to be on the same filesystem.
