[PATCH] append multiple search domains to CISCO_DEF_DOMAIN

[samplinerD at gmail.com (Daniel Sampliner)]

Using globalprotect protocol, if we receive XML with:
<dns-suffix>
        <member>apple.foo.bar</member>
        <member>orange.foo.bar</member>
        <member>banana.foo.bar</member>
</dns-suffix>

CISCO_DEF_DOMAIN environment variable sent to vpnc-script will only
contain the first domain "apple.foo.bar."
This patch combines them all into one single space-separated string
(this behavior matches that of pulse protocol, but I don't have cisco
VPN to test behavior there).
