Add note for printing all dbgmsg entries on FreeBSD

Browse Source 
I looked for a bit, and couldn't find any documentation on
how to print all logged dbgmsg entries, just messages since
the DTrace probe started, until @allanjude kindly pointed me
toward the sysctl.

So let's add that note where the DTrace probe is mentioned for
FreeBSD, so other people can find it.
