Rework on build.sh

[molBR]

Hey, I grew interest on this project. Tried to help with the PR#9 but still facing some problems. Mainly because the script.sh does a lot of work.
Im releasing a new PR to try to fix the pipeline, but still ,it shows that the script needs work. I'm building this issue to check your thoughts on it. The build.sh:

Clones the entire Netdata repository with full history
Checks out submodules recursively
Compiles Netdata from source (C/C++ compilation)
Installs and removes multiple build dependencies

When building for ARM architectures via QEMU emulation, these operations are significantly slower, causing the build to exceed timeout limits or consume excessive resources.

Would like to know your thoughts.

Two options that I can think of:

• Exclude arm as a temporary fix.
• Instead of building everything from scratch, extend the official NetData docker images... The reason that these images exist is that 1) back then official NetData images did not exist 2) they don't allow override via env vars.

1 might not work.
2 was the idea of the PR actually

RE: 2-

Your Dockerfile is still referencing FROM debian:bullseye

Why don't we just do FROM netdata/netdata:version ? That would simplify things a lot, no?
