blobcli: uuid xattrs should be printed as strings

Browse Source 
At the time of commit d1d22046df, xattr UUIDs were stored as
strings, not as `struct spdk_uuid`. That continues to be true today.
As such, bs_dump_xattr should be treating UUID XATTR values as strings
rather than as `struct spdk_uuid`.

This fix does verify that the UUID string is a well-formed UUID before
printing it. If it is not well-formed, "? Invalid UUID" is printed
along with the raw bytes.
