Make quoting of `arch` array contents uniform across all packages.

This adds single quotation marks where there were previously none.
Make quoting of `groups` array contents uniform across all packages.

This adds single quotation where there were previously none. For future
reference, this was run:

    sed -i "/groups=/s/\((\| \|)\)/&'/g;
            /groups=/s/)'/')/g;
            /groups=/s/ /' /g;
            /groups=/s/''/'/g" */PKGBUILD

(I realize that could have been more elegant.)
