get.sh getjdkbinary() not correct uncompressing temurin debug-image and does not handle static-libs archive

[andrew-m-leonard]

During Reproducible build testing (issue) it was discovered the expanded jdkbinary folder for j2sdk-image is incorrectly overlaying Temurin debug-image and also copying the contents
if the static-libs archive which currently getjdkbinary() does not handle.

This highlights two issues:

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