buildlet: enable core dump creation on container VMs

Container-optimized OS sets kernel.core_pattern = "|/bin/false",
effectively disabling core dump creation regardless of RLIMIT_CORE.

We have tests that want to analyze core dumps, so reset core_pattern
back to the default value on boot.

For golang/go#25218.
