Fix some output issues in ipptool introduced by migrating to the cupsFile API.

Have cupsFilePuts and cupsFilePrintf flush output on stdio files (keeps with
expectations when moving from stdio calls).

Update IPP tests to point to the right specs and sections, and fix IPP/1.1
tests WRT job progress attributes (which can have "no-value" out of band values
instead of integers).

Add an "lpstat -e" test.

Update test output to conform to HTML 5.

Copy all log files to HTML report and test directory.

Clean out old log and report files in test directory after a failed run.
