Skip . and .. in plugin loader and trigger error on failed plugin load.
Skip . and .. in plugin loader and trigger error on failed plugin load.

Fix from field testing.  Need to skip "." and ".." directory entries
when loading plugins from /lib/finit/plugins.  Also, trigger an error
when a required plugin fails to load.  We need to print to console
since syslogd has not started yet.
