[Crash-utility] [PATCH] RESEND: Suppress lkcd_speedo() spinner in redirected output

[Sam Watters]

Resent using a benign email client

When redirecting output to a file or script the 'spinner' written by the
lkcd_speedo() function complicates parsing output.

Currently the spinner is only suppressed if crash is run with the '-s'
option or the command 'set silent on' has been executed. The change in
this patch suppresses the spinner when the output is redirected to a
pipe or file.
