[PATCH 1/2 v2]: clean-up setfiles source code and document two options

[Guido Trentalancia <guido@trentalancia.com>]

RE-SUBMISSION (originally submitted on Sun, 20 Feb 2011 09:56:48 +0100)

Minor improvements and clean-ups to the setfiles source code
(policycoreutils):

- removed unused code for undocumented and no-op "-i" option;
- document syntax of "-f" option;
- document syntax of "-p" option in secondary usage case (i.e. with
"-s");
- substitute variable name with parameter name in usage printout for
"-r" option;
- remove a few misplaced spaces from the usage printout for better
formatting.
