[Buildroot] [PATCH 1/1] package/runc: add an option to build a non-static runc

[James Peach <jorgar@gmail.com>]

From: James Peach <jpeach@apache.org>

The systemd cgroup driver is compiled out of static builds of
runc so some users will need a non-static build. Add an option
to control whether the runc should be static or not, and default
it to true for compatibility with existing configurations.
