Subject: [PATCH] Disable exporting vendor-dbx to MokListXRT

As the vendor-dbx grows, it caused some problems when writing such
a large variable. Some firmwares lie the avaiable space(*1) , and
some even crash(*2) for no good reason after the writing of
MokListXRT. Both shim and kernel don't rely on MokListXRT to block
anything, so we just stop exporting vendor-dbx to MokListXRT to
avoid the potential hassles.
