Disable -fghci-leak-check in DEBUG mode

The DEBUG compiler's GHCi still leaks. This commit suppresses
testsuite failures due to this leak. See #15372.

+# Note [Disabling ghci-leak-check]
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+# The -fno-ghci-leak-check is because this test prints the current GHC settings
+# and the ghci-leak-check is turned off in DEBUG mode. See #15372. So we need to
+# turn it off in non-DEBUG mode, too, so that one stdout works for both modes.
+# After #15372 is fully fixed, these "extra_hc_opts" should be removed.
