tests fail under docker environment

[shawnlaffan]

We are seeing test failures in the Strawberry Perl 5.36 builds. Test log below (also reported in StrawberryPerl/Perl-Dist-Strawberry#66).

The first failure is at Line 82, after which the code dies.

Win32API-Registry/t/test.t

Lines 80 to 84 in 450c70c

	while( 0 == $nvals ) {
	$ok= RegEnumKeyEx( $hkey, $nkeys-2, $key2, $klen2=2*$zero,
	[], $class2, $clen2=1*$zero, $time );
	$ok or die "Can't find key with values: ",regLastError(),"\n";

This could be an issue with docker, or the test expectations need to be updated for the docker environment. If I copy the perl stack from docker to my local machine then all Win32API::Registry tests pass.

I don't know the ins and outs of the docker system but I'm happy to run any debugging steps you can suggest.

The docker setup is at https://github.com/StrawberryPerl/spbuild if useful.
