The logic seems quite simple,
but I am not quite sure which file is still valid?


[1] signing_key.pem - OK, this should be certs/signing_key.pem
                         and removed by 'make mrproper'

[2] signing_key.priv - deprecated by commit fb1179499134 ?

[3] signing_key.x509 - OK, this should be certs/signing_key.x509
                         and removed by 'make mrproper'

[4] x509.genkey - this is an intermediate file for generating signing_key.pem,
                  but unneeded for installing external modules.
                  Does it make more sense to delete this by 'make clean'?

[5] extra_certificates - I am not sure where this is generated, and used

[6] siging_key.x509.keyid - same as [5]

[7] signing_key.x509.signer - same as [5]
