[PATCH] codeparser: Fix var_execs to append to execs, not references

[Richard Purdie <richard.purdie@linuxfoundation.org>]

When using the "execs" information in new code, it became clear that
the returned data was incorrect and there were missing exec'd functions.
This corrects the error and changes one of the test results to match
the correct behaviour.
