erofs-utils: mkfs: use extended inodes when ctime is set
Currently mtime is effectively ignored because most inodes are compact.
If mtime was set, and it's different from the build time, then extended
inodes should be used instead.
To guarantee that timestamps do not cause extended inodes, a fixed
timestamp should be used (-T). Additionally, a new --ignore-mtime option
has been added to preserve the old behavior.
