Derek Fawcus 96c524990b 'slabtop -o' with stdin not a tty would complain ...

When the command is executed in one shot mode (-o) with stdin
being something other than a terminal,  the tcgetattr() call
would fail,  and generate an error message. e.g.:

slabtop: terminal setting retrieval: Inappropriate ioctl for device
 Active / Total Objects (% used)    : 905319 / 915886 (98.8%)
