efi_loader: Fix efi_install_configuration_table

So far we were only installing the FDT table and didn't have space
to store any other. Hence nobody realized that our efi table allocation
was broken in that it didn't set the indicator for the number of tables
plus one.

This patch fixes it, allowing code to allocate new efi tables.
