Fix some shellcheck warnings

Note: This does not modify the configure script, which is a source of a
lot of the remaining shellcheck warnings, because it comes from autoconf
and so it makes little sense to try to fix it here.

Also, it does not modify the scripts in contrib, because they possibly
are maintained at some other place. Similarly with the other scripts
that don't appear to be called from any of the makefiles.
