fat: propagate 64-bit inode timestamps
Now that we pass down 64-bit timestamps from VFS, we just need to convert that correctly into on-disk timestamps. To make that work correctly, this changes the last use of time_to_tm() in the kernel to time64_to_tm(), which also lets use remove that deprecated interfaces. Similarly, the time_t use in fat_time_fat2unix() truncates the timestamp on the way in, which can be avoided by using types that are wide enough to hold the intermediate values during the conversion.
