YAML::LibYAML patch

[Tina Müller <forum@s05.tinita.de>]

Hi,

I think starting with libyaml 0.2.2 the following part of
this patch is not necessary anymore:

https://salsa.debian.org/perl-team/modules/packages/libyaml-libyaml-perl/blob/master/debian/patches/system-libyaml.patch#L36

These are the related commits in libyaml:
https://github.com/yaml/libyaml/commit/56400d976a1999156b1abfd674c3122843980260
