shim: add HSIStatus feature
hughsie asked me if I can make shim tell userland what kinds of accesses
are allowed to the heap, stack, and allocations on the running platform,
so that these could be reported up through fwupd's Host Security ID
program (see https://fwupd.github.io/libfwupdplugin/hsi.html ).
This adds a new config-only (i.e. not a UEFI variable) variable
generated during boot, "/sys/firmware/efi/mok-variables/HSIStatus",
which tells us those properties as well as if the EFI Memory Attribute
Protocol is present.
