vdso: Complete the conversion to 32bit syscalls

This patch series is a follow up to "lib/vdso, x86/vdso: Fix fallout from generic VDSO conversion" [1]. The main purpose is to complete the 32bit vDSOs conversion to use the legacy 32bit syscalls as a fallback. With the conversion of all the architectures present in -next complete, this patch series removes as well the conditional choice in between 32 and 64 bit for 32bit vDSOs. This series has been rebased on linux-next/master.
