vdso: Remove struct getcpu_cache
The cache parameter of getcpu() is useless nowadays for various reasons.
* It is never passed by userspace for either the vDSO or syscalls.
* It is never used by the kernel.
* It could not be made to work on the current vDSO architecture.
* The structure definition is not part of the UAPI headers.
* vdso_getcpu() is superseded by restartable sequences in any case.
Remove the struct and its header.
As a side-effect this gets rid of an unwanted inclusion of the linux/
header namespace from vDSO code.
