1) Rename _require_log_writes_dax to _require_log_writes_dax_mountopt.
2) Make _require_log_writes_dax_mountopt check if old or new dax option
is supported.
3) generic/470 takes use of _require_log_writes_dax_mountopt.

Some tests(e.g. ext4/035) cannot include dax option(dax=inode/dax=never
is OK) so make _exclude_scratch_mount_option() and _require_dm_target()
check if old dax or new dax=always option is not defined in $MOUNT_OPTIONS.
