mb/getac/p470: Null-terminate ec_id string buffer

The EC ID of the ECDT needs to be null-terminated (see ACPI specification,
section 5.2.15), which currently isn't being done due to an off-by-one
error. strncpy() is bug-prone exactly because of issues like this, so just
skip it entirely and use memcpy() instead.
