Thomas Perale c9659fd9e8 package/heirloom-mailx: import patches from Debian
In Buildroot there are multiple way to apply patches on a package [1]

- Adding `.patch` file in the package directory.
- Define `<pkg>_PATCH` variable with the location of the patch tar.gz.
  It used to download Debian patches tarball.
- Implement custom patching logic with `PRE`/`POST` patches hooks.

To make the CycloneDX SBOM generation not dependant on downloading the
packages, the two last options have the downside of not appearing on the
generated SBOM.

The heirloom-mailx package is downloading a tarball from the Debian
mirror with the `<pkg>_PATCH` method [2].

To improve the tracking of the patched vulnerabilities for the
heirloom-mailx package this commit import the patches previously
downloaded with the `_PATCH` variable in the Buildroot tree. This allows
to add the `CVE:` trailer [3] on the patches that fix vulnerabilities to
better track which patch is fixing the vulnerability.
