tests: ignore code coverage/profiling failure messages

The Hydra buildfarm provides code coverage analysis.  For some reason,
in some test cases, code coverage data seem to be incompatible, and
generate error messages at parser run-time.  Ignore these messages so
that (i) these tests do pass, (ii) coverage results be provided by
Hydra.

* tests/local.at (AT_PARSER_CHECK): Ignore messages for failed merges
of code coverage/profiling results.
