rpm: Add rpm patch to fix git_strerror issues

Remove the optimzation append from recipe and add the patch that is in the rpm
cvs repo, http://www.mail-archive.com/rpm-cvs@rpm5.org/msg08907.html. The -O2
optimzation append is removed since it can limit debugging options that are
provided when -O0 is used.

This was tested by setting: SELECTED_OPTIMIZATION = "-O0"
