uat: fix memleak after parsing and on errors

Memleaks could occur in these scenarios:
 - Two consecutive fields fail in their chk callback, overwriting the
   first heap-allocated error message.
 - After parsing one record, the internal record was never freed.
 - Syntax errors abort the parsing process and leaks the record and
   current field value.

These leaks will only happen at startup, when the UAT files are read or
when UAT strings are loaded (e.g. from the ssl.keys_list preference).
