[LTP] [PATCH 3/3] lib/vdso: remove struct arch_vdso_data from vdso data struct

[Heiko Carstens <hca@linux.ibm.com>]

Since commit d60d7de3e16d ("lib/vdso: Allow to add architecture-specific
vdso data") it is possible to provide arch specific VDSO data.

This was only added for s390, which doesn't make use this anymore.
Therefore remove it again.
