ruby: update to 2.4.0

Existing version of ruby-native (2.2.5) was crashing on my machine (and others' too),
yet a functional ruby is necessary to upgrade webkit to a version that less vulnerable
to Spectre.

I've performed the update by copying the ruby recipe directory over from the current
pyro tree; if you want to see the list of specific commits, issue this command:
