[11u] RFR: JDK-8252258: JDK-8242154 changes the default vendor

[Andrew Hughes]

Bug: https://bugs.openjdk.java.net/browse/JDK-8252258
Webrev: https://cr.openjdk.java.net/~andrew/openjdk11/8252258/webrev.01/

This is an 11u only fix.

JDK-4947890 was partially backported during the 11.0.8 cycle,
causing a regression in the default vendor name.

In the partial backport, under the bug JDK-8242154 [0],
the default defines for VENDOR, VENDOR_URL and VENDOR_URL_BUG
are removed from System.c. However, only the default values
for VENDOR_URL and VENDOR_URL_BUG are transferred to
make/autoconf/version-numbers.

The result is that the default vendor changes from
"Oracle Corporation" in 11.0.7 to "N/A" in 11.0.8:

With a local build of 11.0.7-ga:

$ ~/builder/11u/images/jdk/bin/java -version
openjdk version "11.0.7-internal" 2020-04-14
OpenJDK Runtime Environment (fastdebug build 11.0.7-internal+0-adhoc.ahughes.jdk11)
OpenJDK 64-Bit Server VM (fastdebug build 11.0.7-internal+0-adhoc.ahughes.jdk11, mixed mode)

$ ~/builder/11u/images/jdk/bin/java -XshowSettings:properties -version 2>&1 | grep java.vendor
java.vendor = Oracle Corporation
java.vendor.url = http://java.oracle.com/
java.vendor.url.bug = http://bugreport.java.com/bugreport/

With the system install of 11.0.8-ga:

$ /usr/lib/jvm/java-11-openjdk/bin/java -version
openjdk version "11.0.8" 2020-07-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.8+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.8+10-LTS, mixed mode, sharing)

$ /usr/lib/jvm/java-11-openjdk/bin/java -XshowSettings:properties -version 2>&1 | grep java.vendor
java.vendor = N/A
java.vendor.url = https://openjdk.java.net/
java.vendor.url.bug = https://bugreport.java.com/bugreport/
java.vendor.version = 18.9

I don't believe we should be changing these defaults in a maintenance
release.  The webrev linked above changes COMPANY_NAME to "Oracle
Corporation" to resume the previous behaviour and I intend to flag
this as jdk11-critical-request once reviewed, as it's a regression.
