* mount, s3: clarify allowOthers requirement and bucket name error
`weed mount -allowOthers` defaults to true. On Linux, a non-root
user's mount then needs `user_allow_other` in /etc/fuse.conf, but the
help text only said "allows other users to access the file system".
Say so in the help, and point at -allowOthers=false.
Also fix the grammar of the bucket name length error ("must between
[3, 63]" -> "must be between 3 and 63").
Help and error text only; no behaviour change.

* s3: normalize the remaining VerifyS3BucketName error messages
The length message was clarified; the rest of the function still had
inconsistent phrasing ("name must start", "cannot be ip addresses",
"prefix xn-- ... in bucket prefix"). Align them on "bucket name ..."
wording matching the AWS bucket naming rules.
