Support non-cached entries in getauxval
Previously the getauxval implementation was limited to the auxiliary vector entries cached in _dl_auxvt. To also support entries outside of that cached subset, store the start address of the auxiliary vector, and if an uncached entry type is encountered search the entire auxiliary vector.
