syscons: add deprecation notice

syscons(4) is not compatible with UEFI, does not support UTF-8, and is
Giant-locked.  There is no specific timeline yet for removing it, but
support for the Giant lock is expected to go away in one or two major
release cycles.  Add a deprecation notice to avoid surprises, and help
ensure that any material deficiencies in vt(4) become known.
