Eliminate magic numbers indicating maximum column sizes in print.c
Without this the magic numbers need to be kept in sync with the maximum
length of the strings printed in the corresponding column. if not, an
overflow and a nasty ' '-storm occur on executing flashrom -L.
Corresponding to flashrom svn r1318.
