Label /etc/rsyslog.d as syslog_conf_t 

This is a minor update of the last attempt at this patch.

Changes in .fc to label /etc/rsyslog.d(/.*)? as syslog_conf_t so all rsyslog config files are labeled syslog_conf_t (not just /etc/r?syslog.conf).  Update .te file to allow rsyslog to read the directory now labeled syslog_conf_t (files of this type were already readable).  Final (and new) change is in logging_admin_syslog interface so files_etc_filetrans now includes the optional filename so /etc/r?syslog.conf would be labeled correctly when created in etc_t.

The overall goal of this patch is that a domain using the logging_admin_syslog is able to create/edit files in /etc/rsyslog.d and they get created as syslog_conf_t AND other files created in /etc (or other etc_t labeled directory) don't get created with the syslog_conf_t type as they are not necessarily syslog configuration files.
