build.gradle fix for Apache 2.4 in otel-webserver-module

Hi

I was working with the webserver-module and compiling it to test it and found a problem.

The current build.gradle file can't compile Apache 2.4 in the webserver container. The APR dependencies are not copied.

I was able to fix it by just including "inputs.dir bundleAprSources" at the beginning of the task configureApache24. Maybe this can be added to the current graddle file.
