Rebuild_Same_JDK_Reproducibility_Test JDK shows extra debugimage and staticlibs folders

[andrew-m-leonard]

Looks like the original JDK is comparing one folder too high?

The problem is in fact in the aqa-tests/get.sh getjdkbinary() uncompression of the upstream build artifacts, the extra
jdk-21.0.6+2
jdk-21.0.6+2-static-libs
folders within the j2sdk-image directory are from copying the contents of the debugimage and static-libs archives into the existing j2sdk-image folder created from the jdk archive expansion.
This is happening for two reasons:

• Temurin debug-image archives have 2 top-level folders rather than the 1 that IBM semeru/openj9 has, and only 1 was being removed
• The getjdkbinary method does not know about the static-libs folder and as a result copies the folder to within the j2sdk-image folder
