community/pass: add coreutils dependency

Pass uses the tr graph character class which isn't currently supported in Busybox tr but is supported in GNU tr. The absence of a tr with graph character class causes tr to use the literal characters '[:graph:]' instead of a character class which causes pass to generate very weak passwords. Add coreutils as a dependency so pass can use a tr implementation with the graph character class support.
