Dependencies for the package build should be here

https://github.com/vyos/vyos-build/blob/c678188cdad6e7907c901a1030e412ba730660ce/scripts/package-build/libpam-radius-auth/package.toml#L6-L10

I'm not sure that this is referenced in the docuementation. As specified in the linked phabricator issue, I was following the documentation from https://docs.vyos.io/en/latest/contributing/build-vyos.html#build-packages which specifies that you should just be able to run the dpkg-buildpackage command.

That being said, if the correct way to do this is with the build.py scripts, I still get this error in the container when running the script.

I can add that extra dependency to this PR, but we may want to also consider updating the relevant documentation with reference to the build.py script.

How do you build the packages?

I do use the current docker image and after changing into /vyos/scripts/package-build/libpam-radius-auth run ./build.py and it compiles fine (the documentation needs updating indeed).

For me it's the packages libcap-ng-dev and libcap-dev that are installed as dependencies of libaudit-dev as it seems and they are installed when running ./build.py

before:

$ apt list --installed 2>/dev/null | grep 'libcap.*dev'
<nothing>

running ./build.py:

...
The following NEW packages will be installed:
  libaudit-dev libcap-ng-dev libpam0g-dev
The following additional packages will be installed:
  libcap-dev
...
dpkg-buildpackage: info: full upload; Debian-native package (full source is included)
I: Cleaned up build dependency packages

$ apt list --installed 2>/dev/null | grep 'libcap.*dev'
libcap-dev/stable,now 1:2.66-4 amd64 [installed,automatic]
libcap-ng-dev/stable,now 0.8.3-1+b3 amd64 [installed,automatic]
...

Are these packages not installed?

The decision is to actually remove build dependencies from the image when they can be easily handled by build.py, so this PR goes againt that idea. Thanks for the effort, though!
