LOG: [lldb] Add zlib to version -v output (#174753)

I know this is required for at least one feature, because
TestSectionAPI.py has failures if zlib isn't enabled. So I think it's
useful for users to be able to check.

Now that it's in the config, I have also used it to make a test
annotation so we don't get the failure in TestSectionAPI.py when zlib is
disabled.

Which for future reference was:
Traceback (most recent call last):
File
"/home/davspi01/llvm-project/lldb/packages/Python/lldbsuite/test/decorators.py",
line 452, in wrapper
    return func(self, *args, **kwargs)
File
"/home/davspi01/llvm-project/lldb/test/API/python_api/section/TestSectionAPI.py",
line 67, in test_compressed_section_data
self.assertEqual(section_data, [0x20, 0x30, 0x40, 0x50, 0x60, 0x70,
0x80, 0x90])
AssertionError: Lists differ: [] != [32, 48, 64, 80, 96, 112, 128, 144]

As it failed to decode the compressed section.
