bash->bourne script cleanup

Many of the scripts in the openvpn source have their shell set to
/bin/bash, but only two use bash features. The attached patch (against
openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for
better portability. The only scripts that actually require bash are
contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable
indirection feature.
