There are quite a few auxvec.h headers. Mark all of them maintained
as part of 'EXEC & BINFMT API, ELF'.

The auxvec.h header is a more fitting place for these definitions.

Upcoming changes will create architecture-specific asm/auxvec.h headers.
Add asm-generic infrastructure to handle the fallbacks for architectures
which are not migrated yet and those which won't require their own
definition.
Extend the list of includes in linux/auxvec.h to cover all potential
low-level auxvec.h headers.

With the introduction of asm-generic/auxvec.h, this header unnecessary.

There is nothing userspace can do with this value. In the kernel is
always combined with AT_VECTOR_SIZE_BASE, which is not exposed to
userspace and also changes from time to time.
Move the symbol to a kernel-internal header.
