vdso: Switch get/put_unaligned() from packed struct to memcpy()

Type punning is necessary for get/put_unaligned() but the use of a packed
struct violates strict aliasing rules, requiring -fno-strict-aliasing to be
passed to the C compiler.

Switch to using memcpy() so that -fno-strict-aliasing isn't necessary.
