Introduce a temporary gpg key pair to sign the repository, with
"starlingx" as its password.
Insert a private key into stx-aptly to sign repositories;
Insert a public key into stx-builder, stx-pkgbuilder to use the signed
repository.
Upgrade stx-aptly from buster to bullseye.
Modify the dockerfile of stx-builder to avoid using command
`lsb_release -cs`. This command is not always work in order, it
may return "n/a" thus cause the image build error. Replace it
with "bullseye".
TestPlan:
Pass: Repository can be signed(aptly);
The signed repository can be accessed(builder, pkgbuilder)
