set spool_dir seltype to syslogd_var_lib_t

when selinux is enabled and enforcing. For some reason, this directory
does not have the correct seltype in RHEL <= 7 and using disk queues or
.state files does not work.

Allow option to avoid loading imfile module twice.

This throws a warning with version 8 of rsyslog.

adding that it will still work the old way (adding modload imfile to the
begining of the imfile).
