objspace_dump.c: skip dumping method name if not pure ASCII

Sidekiq has a method named `❨╯°□°❩╯︵┻━┻`which corrupts
heap dumps.

Normally we could just dump is as is since it's valid UTF-8 and need
no escaping. But our code to escape control characters isn't UTF-8
aware so it's more complicated than it seems.

Ultimately since the overwhelming majority of method names are
pure ASCII, it's not a big loss to just skip it.
