When building an SDK (with populate_sdk), all '-dev' packages are
installed. And empty 'openssh-dev' package would pull in 'openssh-sshd'
package even if our image is only depending on 'openssh-sftp'.
This causes a conflict with 'dropbear' server, which is only using
openssh-sftp.
Fix:
Problem: package dropbear-dev-2020.81-r0.4.cortexa7t2hf_neon requires dropbear = 2020.81-r0.4, but none of the providers can be installed
- package dropbear-2020.81-r0.4.cortexa7t2hf_neon conflicts with openssh provided by openssh-8.9p1-r0.7.cortexa7t2hf_neon
- package openssh-8.9p1-r0.7.cortexa7t2hf_neon conflicts with dropbear provided by dropbear-2020.81-r0.4.cortexa7t2hf_neon
- package openssh-dev-8.9p1-r0.7.cortexa7t2hf_neon requires openssh = 8.9p1-r0.7, but none of the providers can be installed
- conflicting requests
