s390/vdso: map vdso also for statically linked binaries
s390 does not map the vdso for statically linked binaries, assuming that this doesn't make sense. See commit fc5243d98ac2 ("[S390] arch_setup_additional_pages arguments"). However with glibc commit d665367f596d ("linux: Enable vDSO for static linking as default (BZ#19767)") and commit 5e855c895401 ("s390: Enable VDSO for static linking") the vdso is also used for statically linked binaries - if the kernel would make it available. Therefore map the vdso always, just like all other architectures.
