[Buildroot] [PATCH 2/3] package/runc: fix shared only build when libseccomp is enabled.

[Romain Naour <romain.naour@gmail.com>]

When BR2_PACKAGE_LIBSECCOMP is set, the go build system will try to
find static library libseccomp.a since "static_build" and
"extldflags '-static'" are used.

Link runc statically only for static only build and prefer dynamic
linking otherwise.
