icu: backport fix for rare random genrb segmentation fault

* sometimes I've seen it also reporting "Bus error" instead of segmentation fault

* upstream bug report:
  https://unicode-org.atlassian.net/browse/ICU-21175

* on 80 core machine it failed 11 times in 1000 rebuilds of icu in various files:
  icu.019.stderr.compile:make[1]: *** [out/build/icudt66l/windowsZones.res] Segmentation fault
