Update nload to 0.7.4.

per maintainer update request by PR 45947.

hanges since 0.7.2:
 * Newer Linux kernels use 64 bit counters, which caused traffic to increase by
   4GB on every refresh (see Debian bug #651848)
 * Fix calculation of traffic and data units (thanks to Kirby Zhou, see also
   Debian bug #586943)
 * Fix memory leak in BSD network device detection
 * Workaround for faulty newwin() in ncurses 5.8
 * Correctly escape minus signs in man page
