md-create: specify that the "chunk" parameter should be absent for RAID1

Browse Source 
Recently, mdadm has started (correctly) rejecting the "chunk" parameter
for RAID1; see e.g. <https://bugzilla.redhat.com/show_bug.cgi?id=1987170>.
Update the documentation accordingly, and in the mdadm test case, move the
"chunk:65536" parameter from a RAID1 creation command to a RAID5 one.
