Add libc6-dev-i386 package

[arturkow2000]

libc6-dev-i386 is required to build i386 edk2 code

This package is installed separately because attempt to do this in a single command resulted in failure:

Suggested change

&& DEBIAN_FRONTEND=noninteractive apt-get -qqy install \

No need to do apt-get install again. SImply add the module to the list.

Why would firmware depend on system libraries in the first place? Are there any intermediate build tools built as 32b binaries on 64b system? If this is caused by firmware code then there is something wrong with that code, probably wrong or missing header file, and that is what should be fixed, not the Docker image. (Also, please don't put links nor logs in the response to this comment, I'm aware of what lead to this change, but NDA 🤐).
