Re-remove more iast .so files

[avara1986]

APPSEC-58746

PR DataDog/dd-trace-py#12774 was merged to address this.

What does this PR do?

Re-removes the ddtrace/appsec/_iast/_ast/iastpatch*.so file from the python layers.

Motivation

A change was made by the appsec team to the python tracer which inadvertently caused an import attempt on ddtrace/appsec/_iast/_ast/iastpatch*.so. This import would fail when using our python layer. We remove this file because it is large and iast doesn't work in serverless anyway.

Testing Guidelines

There is another open PR in the python tracer DataDog/dd-trace-py#14420 which will add explicit testing to ensure none of our removed files get imported.

Thank you so much for doing this! It looks like we can now decrease our expectations of unzip layer size in our tests. Would you mind changing the 23 to a 22 in this file as part of this PR?

MAX_LAYER_UNCOMPRESSED_SIZE_KB=$(expr 23 \* 1024) # 23552 KB
