[RFR] [8u] 8228469: (tz) Upgrade time-zone data to tzdata2019b

[Andrew John Hughes]

Webrev: https://cr.openjdk.java.net/~andrew/openjdk8/8228469/webrev.01/
Bug: https://bugs.openjdk.java.net/browse/JDK-8228469

This is the regular timezone data update for the next CPU.

The only real difference from the patch for 11 & 14 is that I chose to
keep with rearguard format for now. We can look at backporting
JDK-8212970 for 8u242, but I don't want to make such a change at this
late stage in 8u232.

The effect of this is in make/data/tzdata/africa where the additions for
Morocco don't use a negative offset and the context of the changes being
applied differs slightly (some lines have to be commented out in
rearguard, such as Ireland's negative offset)

The rearguard version was created by downloading the tzdata2019b bundle
and running 'make rearguard_tarballs' as specified in the bug text. This
generated version was then compared against that from jdk11, with the
only difference being those Morocco rules.

The only other trivial change from jdk11 is in
test/java/util/TimeZone/TimeZoneTest.java where the bug ID list is
different. I also took the opportunity to drop the useless @modules line
from there.

Once reviewed, I'll propose this for jdk8u-critical-request.

Thanks,
