 mm/memfd_luo: document preservation of file seals 
Commit 8a552d68a8 ("mm: memfd_luo: preserve file seals") started
preserving file seals across live update and restoring them via
memfd_add_seals() on retrieve, but the DOC header was not updated and
still listed seals under "Non-Preserved Properties" as being unsealed
on restore.

Move the Seals entry to the "Preserved Properties" section and describe
the actual behavior, including the MEMFD_LUO_ALL_SEALS restriction that
both preserve and retrieve enforce.
