    Use env to set environ when starting dnsmasq

    Explictly use env to setup needed environment variables for dnsmasq when
    starting to avoid problems with subprocess mis-interpreting the first
    command line argument as the executable name.

    Also update DnsmasqFilter to accept any command that starts with env
    followed by a set of args that include an equals sign, as long as the
    next arg is the dnsmasq command.

    fixes bug #1073253
