[PATCH] Update auditctl man page for new example on shell escaping.

[Romesh Upadhyay]

This commit will add additional example in auditctl(8) manpage which will
help users to use shell escaping while defining the rules through auditctl
command. As some characters require escaping when invoked from a shell.
It is known issue that shell interpret '>' as redirection which results
in auditctl giving errors like "-F missing operation for auid".
