git-send-email.perl: ensure $domain is defined before using it
valid_fqdn() may attempt to operate on an undefined value if
Net::Domain::domainname fails to determine the domain name. This causes
perl to emit unpleasant warnings.
So, add a check for whether $domain has been defined before using it.
