core_parse: Always fold literal conses
v3_core is careful to always create literals whenever possible.
Correct core_parse so it, too, always creates literals out
of literal conses. With that correction, we can remove the
workaround in sys_core_fold (introduced in 26a5dea3cb5e101)
that handles non-literal flags in a binary.
