8254177: (tz) Upgrade time-zone data to tzdata2020b

[yan-too]

We should catch up timezone data advance: this is tzdata2020b. The patch had one conflict with GendataTZDB.gmk renaming (and no content conflicts there) and a conflict in a test amounted to one symbol change. All relevant regtests do pass AFAIS
