um: remove ARCH_NO_PREEMPT_DYNAMIC

[ Upstream commit 64dcf0b8779363ca07dfb5649a4cc71f9fdf390b ]

There's no such symbol and we currently don't have any of the
mechanisms to make boot-time selection cheap enough, so we can't
have HAVE_PREEMPT_DYNAMIC_CALL or HAVE_PREEMPT_DYNAMIC_KEY.

Remove the select statement.
