build: Remove newer HHVM versions we'll never support

Been failing for months. The believe that, defacto, the only version
we support is HHVM 3.18. Interestingly, that build is failing too,
possibly due to configuration differences between WMF and Travis.
I'll keep it for now, in case wants to try and make it pass.
