[PATCH 4/8] progress.c: call progress_interval() from progress_test_force_update()

Define the progress_test_force_update() function in terms of
progress_interval(). For documentation purposes these two functions
have the same body, but different names. Let's just define the test
function by calling progress_interval() with SIGALRM ourselves.
