Map c (create) log events to w instead of a

Browse Source 
Creating a file is in theory covered by the 'a' permission, however
discussion on IRC brought up that depending on the open flags it might
not be enough (real-world example: creating the apache pid file).

Therefore change the mapping to 'w' permissions. That might allow more
than needed in some cases, but makes sure the profile always works.
