[PATCH 01/11] sandbox: Set the EFI symbols in linker script

[Andrew Scull <ascull@google.com>]

The sandbox doesn't populate the EFI lists so explicitly set the list
start and end symbols to indicate that the lists are empty. This
simplifies the linker scripts, removed references to non-existant
sections and removes '.' prefixed sections that conflicted with clang's
ASAN.
