doc: release: 4.3: deprecate CONFIG_XOPEN_STREAMS (again)

Deprecate the CONFIG_XOPEN_STREAMS Kconfig option in favour of
CONFIG_XSI_STREAMS, which matches the naming conventions of other XSI
Kconfig options and the actual Option Group name in the specification.

Please use CONFIG_XSI_STREAMS instead.
