[PATCH v2 1/7] gitignore: Ignore files generated by "make coverage"

The "make coverage" support added by Thomas Rast in 901c369af5 didn't
contain a corresponding patch to patch .gitignore.

Change gitignore to ignore the *.gcda, *.gcno and *.gcov files
generated by GCC and our coverage invocations.
