maint: tests: ignore code coverage/profiling failure messages

[Akim Demaille]

I installed this in maint.  As a result, Hydra is now 100% green
on maint, http://hydra.nixos.org/build/2514548, and the code
coverage analysis can be consulted.

Obviously XML-related code is poorly covered, but that's because
the test-suite is designed this way (another target, maintainer-xml-check
is there to cover this).  Time permitting, I'll see if there are
simple means to include this in the test suite as run by Hydra.

Subject: [PATCH] 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.
