libstdc++: Fix test that uses C++17 variable template in C++14
This test fails if run with -std=gnu++14 because it should be using
is_convertible instead of is_convertible_v.
libstdc++-v3/ChangeLog:
* testsuite/experimental/propagate_const/observers/107525.cc:
Use type trait instead of C++17 variable template.
