Relax ANNO limitation in test coverage utils
Currently the code to determine whether a particular file attribute
("header") exists assumes an ANNO format of a single line number, but
versions of OTP > 23 return a tuple, so that pattern will never match,
resulting in coverage failing to account for the inclusion of the
`eunit.hrl` file, and then incorrectly calculating the coverage of the
test module as 66%, rather than the expected 100%.
This change relaxes the pattern so that it will also match tuples,
and fixes the eunit coverage test.
