we cannot mock a non existing symlink

my $mocked = Test::MockFile->file( "/abc.txt" );

# then later
symlink( '/somewhere', "/abc.txt" );

# this is failing and not viewing this as a symlink
ok -l $ma->path, 'this is a symlink';

The symlink helper will create a symlink. We have no way to declare a non existing symlink.

I'm not sure that's right...
