Add support for disabling signature verification
Provide a mechanism for a physically present end user to disable signature
verification. This is handled by the OS passing down a variable that
contains a UINT32 and a SHA256 hash. If this variable is present, MokManager
prompts the user to choose whether to enable or disable signature validation
(depending on the value of the UINT32). They are then asked to type the
passphrase that matches the hash. This then saves a boot services variable
which is checked by shim, and if set will skip verification of signatures.
