Cleanup: Define ECGRULESPARSEFAIL for the parser error of cgrules.conf.

Cleanup: Define ECGRULESPARSEFAIL for the parser error of cgrules.conf.

Changelog since v2:
o Define ECGRULESPARSEFAIL for avoiding breaking ABI.

Changelog since v1:
o A new patch [Cleanup: Rename ECGROUPPARSEFAIL to ECGRULESPARSEFAIL.]

Now ECGROUPPARSEFAIL is defined for a parser error of /etc/cgrules.conf and
this patch defines ECGRULESPARSEFAIL for the same value for clarifying its
meaning.
