[Buildroot] [PATCH 1/1] modify site from adoptopenjdk mirror to official hg.openjdk.java.net repository

[Tudor Holton]

Since Java 11 (and possibly earlier), OpenJDK now has its own official
repository at hg.openjdk.java.net which is referenced in all OpenJDK documentation.
This patch brings buildroot into line with that source, reducing the opportunity
for code injection, and allowing consistent patching both across projects and for
patches specific to buildroot environments.

diff -ru shows that the only changes between the downstream and upstream files at
this point in time is the addition of a .hg_archive.txt file,  containing:

repo: fd16c54261b32be1aaedd863b7e856801b7f8543
node: 7b6accc7c009304dd2979ea16c1cb15bf749a1fc
branch: default
tag: jdk-12.0.2+10
tag: jdk-12.0.2-ga

This does, however, change the hash for the tar.gz file (but not for the license).

With respect to the concern regarding upstream hash consistency, we have now been
using these archives for just over a year (since OpenJDK 11) and we haven't seen an
archive hash change in that time.  This was a vast improvement on the previous
Mercurial forest.  /archive is exactly as is sounds.  It's an archive that doesn't
change, which is why it effectively negates the need for a "downstream" mirror.

Tests completed successfully (which is not surprising since there are no code changes here):
