firmware: Add missing attributes to EFI variable attribute print out from sysfs
Some of the EFI variable attributes are missing from print out from /sys/firmware/efi/vars/*/attributes. This patch adds those in. It also updates code to use pre-defined constants for masking current value of attributes.
