Fix compiler unwrapping step in jenkins build scripts for Caffe2/PyTorch on ROCm (#25409)
Summary:
Fix the regex (requires enabling extglob) for two digit clang releases.
While there, also fix it for three digit releases with the hope that I
do not need to touch it for some time.
Unfortunately, this regex requires extglob to be enabled in the shell.
