.spec file for rhel6 rpm, with some config related patches

I created an rpm for rhel6 (which should be aok for centos6 and sl6 as well) so felt like it might be nice to send it through.

I made some config choices which i applied via some patches. That is apache2 (which is all thats available on el6) and postgresql with single mode.

database testing didnt work, so i just sort of carved that out of the build process.

also the dependencies are probably over the top and i turned off the make test part of the build process.

so im summary, not perfect by any means. i have made some choices in the .spec file as to how bricolage will be configured which people may not like... but perhaps someone will find it useful!
