Missing run-time dependencies in packages `ebtables`, `libassuan` and `rpm-ostree`

Describe the bug

The following packages missing some run-time dependencies:

• ebtables: perl
• libassuan: libgpg-error-devel
• rpm-ostree: json-c, libmodulemd, polkit, sqlite, cppunit

When adding package ebtables libassuan rpm-ostree to common/data/packages_minimal.json and make minimal-iso , the following RPMs don't exist in the ISO: perl libgpg-error-devel json-c libmodulemd polkit sqlite cppunit . If you use this ISO to install photon, error will be reported like "xxx can not be found".

It's because photon/support/package-builder/SpecDeps.py can not detect run-time dependency if the dependency is not added to the package spec file by Requires field. And the denpendency will not be copied to ISO.

I'm not sure if there are other packages have the same error.

Reproduction steps

1. add `ebtables` to `common/data/packages_minimal.json`
2. make minimal-iso
3. use ISO to install Photon OS
4. installation failed

Expected behavior

Use above ISO to install Photon OS will succeed.

Additional context

No response

Start by reading photon/support/package-builder/SpecDeps.py, then reproduce the issue by adding the listed packages to common/data/packages_minimal.json and running make minimal-iso. Verify that perl, libgpg-error-devel, json-c, libmodulemd, polkit, sqlite, and cppunit are present in the resulting ISO and that Photon OS installation succeeds.
