Subject: libxl/arm: Fix build on arm64 + acpi w/ gcc 8.2

Add zero-padding to #defined ACPI table strings that are copied.
Provides sufficient characters to satisfy the length required to
fully populate the destination and prevent array-bounds warnings.
Add BUILD_BUG_ON sizeof checks for compile-time length checking.
