Subject: [PATCH] tests: allocators: Fix fdmem test with recent GLib

The test failed with recent GLib, where `g_close` emits a critical
warning on EBADF. Remove the `g_close` check from `test_fdmem` and add
another version that tests `GST_FD_MEMORY_FLAG_DONT_CLOSE`.

We will depend on the Valgrind test run to warn us about leaked FDs.
