linux: Disable ACPI configfs support

This is disabled in IPFire 3.x, and projects such as grsecurity
recommend doing so for security reasons as well. Also, skimming through
our source code, there is no point where this ACPI configfs would have
been explicitly mounted, which leads to the assumption that we never
used it anyway.
