On some old kernel which supports COLLAPSE_RANGE and ZERO_RANGE, but
doesn't support INSERT_RANGE, this case alway fails as:

   QA output created by 499
  +main: filesystem does not support fallocate mode FALLOC_FL_INSERT_RANGE, disabling!
   Silence is golden

fsx print one more line to break the golden image.

To fix this issue, redirect both fsx stdout and stderr to a file,
then check the return value.
