[PATCH v4 1/4] tools/xenstore: minor fix of the migration stream doc

[Juergen Gross <jgross@xxxxxxxx>]

Drop mentioning the non-existent read-only socket in the migration
stream description document.

The related record field was removed in commit 8868a0e3f674 ("docs:
update the xenstore migration stream documentation).
