We were a bit too aggressive in trimming superfluous print messages earlier on. This patch adds a line of output for each iteration of the while loops in the test. The intention is to give the user something useful to indicate test progress without just printing a ton of debug spew. Maybe a future patch can redirect more verbose info to a log file.

The output looks like this::
localhost ~ # FLASHROM="./flashrom" sh flashrom_partial_write_test.sh 
testing flashrom binary: ./flashrom
Running test in /tmp/tmp.4xPejwaADU
ffh pattern written in ff_4k.bin
00h pattern written in 00_4k.bin
Reading BIOS image
