[PATCH linux-cr] send uses_interp=1 to arch_setup_additional_pages

[Serge E. Hallyn]

Because the s390 version won't set up vdso if it is 0.  It
is safe to assume that if we are calling special_mapping_restore()
then there is a vdso in the checkpoint image, and if that is
the case then the checkpointed program was dynamically linked.

Other architectures ignore uses_interp so this shouldn't
matter to them.
