Adjust to shellcheck removal in Alpine. Currently it's still in edge for
x86_64, but installation fails with:
ERROR: unable to select packages:
so:libffi.so.7 (no such package):
required by: shellcheck-0.7.2-r1[so:libffi.so.7]
Use the official static binary release from shellcheck instead of the
Alpine package. Version 0.7.2 is intentionally used instead of latest
8.0.0, since the latter generates a new warning. Let's unbreak CI first
before adjusting to a newer shellcheck version.
