Log Message:
Update fstrm to version 0.6.0.

Upstream changes:
 * This adds a new feature for fstrm_capture. It can perform output
   file rotation when a SIGUSR1 signal is received by fstrm_capture.
   (See the --gmtime or --localtime options.) This allows
   fstrm_capture's output file to be rotated by logrotate or a
   similar external utility. (Output rotation is suppressed if
   fstrm_capture is writing to stdout.)
