efi_selftest: test protocol management
This unit test checks the following protocol services:
InstallProtocolInterface, UninstallProtocolInterface,
InstallMultipleProtocolsInterfaces,
UninstallMultipleProtocolsInterfaces,
HandleProtocol, ProtocolsPerHandle,
LocateHandle, LocateHandleBuffer.
As UninstallProtocolInterface and UninstallMultipleProtocolsInterfaces
are not completely implemented a TODO message will shown for
their failure.
