EFI: Add Data Directory space

Browse Source 
Currently, the PE headers we create in boot/header.S do not allocate
space for any Data Directory entries, as they haven't been needed.

In order to support signatures and compatibility with some loaders, we
need the Data Directory to be populated at least enough to set
DataDirectory.Certs and DataDirectory.BaseReloc.

This patch extends that space enough to include those entries.
