dns_freedns.sh: use grep -E, BRE \| alternation is a GNU extension

Browse Source 
OpenBSD grep treats \| in a BRE as a literal | character, so
_freedns_domain_id never matched any row and every domain lookup
failed with "Domain not found". Switch to ERE with -E, keeping the
parens escaped so the (.*) suffix branch still requires literal
parentheses and does not widen the match (e.g. searching example.com
must not match example.company).
