ACPICA: Apply ACPI_NONSTRING in more places

ACPICA commit 1035a3d453f7dd49a235a59ee84ebda9d2d2f41b

Add ACPI_NONSTRING for destination char arrays without a terminating NUL
character. This is a follow-up to commit 35ad99236f3a ("ACPICA: Apply
ACPI_NONSTRING") where not all instances received the same treatment, in
preparation for replacing strncpy() calls with memcpy()
