testsuite: C++14 vs. C++17 struct-layout-1.exp testing with ALT_CXX_UNDER_TEST [PR94383]

This patch does that, so now when testing against not too old compiler
it can do the -std=c++14 vs. -std=c++17 testing also between under test and
alt compilers.

* g++.dg/compat/struct-layout-1.exp: Use the -std=c++14 vs. -std=c++17
ABI compatibility testing even with ALT_CXX_UNDER_TEST, as long as
that compiler accepts -std=c++14 and -std=c++17 options.
