[Buildroot] [git commit] package/tini: compile executable static

commit: https://git.buildroot.net/buildroot/commit/?id=e4732222e4c863e324771f8be2391764641ceba2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.

Previously, we didn't build statically to avoid problems with
BR2_SHARED_LIBS=y. However, it turns out that tini can successfully link
statically even with glibc and BR2_SHARED_LIBS=y, because libc.a is
still included in staging, and tini doesn't use any NSS functionality.
