Subject: efi_loader: allocate configuration table array

The system table contains a link to the list of configurations tables.
These include the device tree, SMBIOS table, and the ACPI table.

This array is currently statically linked. With the patch it is allocated
as EFI_RUNTIME_SERVICES_DATA. Due to the structure of the system table we
cannot work with a linked list here.
