Drop run_as function in entrypoint

Please note that `run_as` included `sh -c`, which is in any practical sense identical to `eval`, therefore we simplify `occ maintenance:install` to use `eval` instead. I'm no fan of `eval` either, however, since we must construct `$install_options` at runtime there simply is no other way to achieve this with POSIX-alike shells like Debian's Bash POSIX mode, and Alpine's Ash.
