Subject: [PATCH] Box86/64: add pagesize checking

error on box86 which does not support 16K pagesize and install 16K pagesize deb on box64.

The only known ARM desktop system using 16K pagesize is Apple Silicon which CPUs do NOT support 32bit ARM binary execution in hardware so they can never run box86 anyway.
