[Buildroot] [PATCH v2] package/tini: compile executable static

[Simon Rowe]

One usecase for tini is as the init process for a container which has
a single executable and no C runtime library. It therefore needs to be
independent of any C runtime library within the container.

Tested with multiple toolchains and BR2_SHARED_LIBS=y.
