    Fix build of nptl/tst-thread_local1.cc with GCC 12

    The test nptl/tst-thread_local1.cc fails to build with GCC mainline

    because of changes to what libstdc++ headers implicitly include what

    other headers:

    tst-thread_local1.cc: In function 'int do_test()':

    tst-thread_local1.cc:177:5: error: variable 'std::array<std::pair<const char*, std::function<void(void* (*)(void*))> >, 2> do_thread_X' has initializer but incomplete type

      177 |     do_thread_X

          |     ^~~~~~~~~~~

    Fix this by adding an explicit include of <array>.

    Tested with build-many-glibcs.py for aarch64-linux-gnu.
