test case calls CloseHandle on a LoadLibrary handle

In src/test/test_util.c, one of the Windows-specific test cases, test_util_load_win_lib() uses the wrong release function on a dll handle it obtains during the test. This triggers a kernel32 assertion if a debugger is attached.

I could only find this one place; all others either close the handle properly, or leave it hanging until process shutdown. The fix is simple:

diff --git a/src/test/test_util.c b/src/test/test_util.c
index 04ca42d..4bbcedd 100644
