[ruby/psych] Improve libyaml source downloading error messages

Browse source 
People trying to build CRuby by following the instructions in its
[README] have been running into [errors] due to missing `libyaml`
on their system. Let's try to present a better error message when
it happens.

[README]: fb5aa31e2d (how-to-compile-and-install)
[errors]: https://github.com/ruby/psych/issues/552
