syslogd: fix memory leak in casper_ttymsg()
nvlist_take_string_array(9) takes ownership of the array and its
strings. casper_ttymsg() freed neither, leaking memory on every
F_CONSOLE and F_TTY message. On long-running systems with high
error-rate syslog traffic routed to /dev/console, syslogd.casper grew
to hundreds of MB.
Use nvlist_get_string_array(9) to borrow the array instead. Update
casper_wallmsg() similarly.
