loader: fix EFI ACPI detection

Description

loader: fix EFI ACPI detection

lua was previously unable to determine ACPI presence because this
probing was postponed until the final loading and execution of the
kernel.

This patch resolves that by detecting ACPI early (similar to
the order of operations in the legacy i386 loader).
