will be passed to SetVariable() to authenticate the variable.

A signature database variable is associated with a specific guid.
For convenience, if user doesn't supply any guid info, "env set|print -e"
should complement it.

With this patch, when setting UEFI variable with "env set -e" command,
we will be able to
- specify vendor guid with "-guid guid",
- specify variable attributes, BOOTSERVICE_ACCESS, RUNTIME_ACCESS,
respectively with "-bs" and "-rt",
- append a value instead of overwriting with "-a",
- use memory as variable's value instead of explicit values given
at the command line with "-i address,size"
If guid is not explicitly given, default value will be used.
Meanwhile, "env print -e," will be modified so that it will NOT dump
a variable's value if '-n' is specified.
