patch 8.1.1080: when a screendump test fails, moving the file is a hassle
Problem: When a screendump test fails, moving the file is a hassle.
Solution: Instead of appending ".failed" to the file name, keep the same
file name but put the screendump in the "failed" directory.
Then the file name only needs to be typed once when moving a
screendump.
