Subject: [RFC 24/32] hfs, hfsplus: convert to struct inode_time

hfs uses 32-bit integers based at 1904 for inode timestamps, which will
only work until 2040, but the VFS uses struct timespec for timestamps,
which expires even earlier in 2038 on 32-bit CPUs.

This gets us one small step closer to lifting the VFS limit by using
struct inode_time in logfs.
