[PATCH 03/10] um: Split out default elf_aux_hwcap

Setting all auxiliary vector values to default values if one of them
was not provided by the host will discard perfectly fine values.

Remove the elf_aux_platform fallback from the vDSO ones.
As zero is the correct fallback anyways, don't create a new conditional.
