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.
