lib/dns: allow parsing TXT rdata without quote in zone file

Previously, the zone only parsing TXT record with double quote since
most of the example that we found during implementation all use double
quote.

This changes allow non-double quoted text in zone file with consequence
that any spaces will terminated the rdata immediately.
