freifunk-common: neigh.sh: work also with unprettyfied JSON output

Older OLSRd-version outputs JSON humanreadable over multiple lines.
The introduced change in 524439cd1647e5d6d7b48f9c75ec5800a5444109 broke
the output for those users. Fix that be a finer filter regex.
Thanks to Thomas Huehn <[email protected]> for spotting that.
