Sudhakar Kuppusamy 97f7001e19 appended signatures: Create db and dbx lists 
If secure boot is enabled with static key management mode, the trusted
certificates will be extracted from the GRUB ELF Note and added to db list.

If secure boot is enabled with dynamic key management mode, the trusted
certificates and certificate/binary hash will be extracted from the PKS
and added to db list. The distrusted certificates, certificate/binary hash
are read from the PKS and added to dbx list. Both dbx and db lists usage is
added by a subsequent patch.

Note:
- If db does not exist in the PKS storage, then read the static keys as a db
  default keys from the GRUB ELF Note and add them into the db list.
- If the certificate or the certificate hash exists in the dbx list, then do not
  add that certificate/certificate hash to the db list.
