Do not remove file that do not exist
<oo-accept-broker> more rhel/fedora reconciliation, cleanup

Modify packages list for check_packages since these are divergent
between rhel and fedora

use oo-ruby instead of inline ruby wrapper, since it already exists
and will be updated independent of this script
<oo-accept-broker> replace safe_ruby fxn wrapper with oo-ruby

instead of calling oo-ruby from safe_ruby function wrapper, just
replace the one safe_ruby call with oo-ruby and replace redundant
safe_ruby function defs in oo-accept-broker

I don't know why I didn't do this in my last commit. :-/
<oo-accept-broker> test for oo-ruby in path

This script depends on the oo-ruby wrapper now; if oo-ruby isn't found
in the path, that counts as a failure in the check_ruby_requirements
test

Also minor whitespace cleanup
