LOG: [libcxx] Fix deprecation warning by suppressing deprecated around
__test_has_construct.

In C++17 some tests started failing after a521532aa16df2c06c91488f2a4e787586f0a611. This fixes those errors by suppressing the deprecation warning when calling `construct` in `__test_has_construct`. This is the same solution as `__has_destroy_test` already uses.
