[jdk8u-dev] RFR: 8287191: [8u] Build failure without git information

[wxiang]

In 8u332, the commit "8210283: Support git as an SCM alternative in the build” used git as an SCM.
In the source package “https://github.com/openjdk/jdk8u/archive/refs/tags/jdk8u332-ga.tar.gz”， 
the .git directory has been removed in the source package. 

When we compile JDK with the source code from the package, we get the below error: 
``` 
Building 'linux-x86_64-normal-server-release' (matching CONF=release)
