LOG: [libc++][test] Do not test Clang bug in `is_constructible.pass.cpp` (#105964)

A comment in `is_constructible.pass.cpp` suggests that Clang is
non-conforming in accepting construction of `const int&` from
`ExplicitTo<int&&>`.

This PR changes the test to expect the standard-conforming behavior,
which makes the test pass on MSVC.
