getrandom vDSO implementation requires __put_unaligned_t() and
__put_unaligned_t() but including asm-generic/unaligned.h pulls
too many other headers.
Follow the same approach as for most things in include/vdso/,
see for instance commit 8165b57bca21 ("linux/const.h: Extract
common header for vDSO"): Move __get_unaligned_t and __put_unaligned_t
into a new unaligned.h living in the vdso/ include directory.
