This pull request improves the available OpenRC initscripts in
contrib/init.
The first commit (737feadff7c026412039774de0d10931fe0c5bcc) reworks
checkconfig() to not fail if both rpcuser and rpcpassword
are unset, because this implies that bitcoind shall use the .cookie
file for RPC authentication. Currently, the initscript does not allow
starting bitcoind without a set rpcuser and rpcpassword.
The second commit (95f97111dd27f32dfcb461c9dd6890aa8d1355ed) simply quotes some unquoted variables.
