Include hidden files in the zip

[sam2kb]

Without the hidden files some packages will be broken. You gotta change this line to be zip -r /io/lambda.zip * .[^.]*

Also I'd rather use this as a layer, so we need to zip the files in a python/ directory like so

cd tmp411
zip -r /io/lambda.zip *

cd ..
mv tmp411 python
zip -r /io/lambda-layer.zip python
