Add -Wstrict-aliasing to vector-struct-1.C testcase

As noticed by Marek Polacek in https://gcc.gnu.org/pipermail/gcc-patches/2024-February/645836.html,
this testcase was not failing before without -Wstrict-aliasing so let's add that option.

Committed as obvious after testing to make sure the test is now testing with `-Wstrict-aliasing` and `-flto`.

gcc/testsuite/ChangeLog:

	* g++.dg/torture/vector-struct-1.C: Add -Wstrict-aliasing.
