src/arch/x86: Build mainboard acpi_tables source if present

Current build rules require adding blank acpi_tables in some of the
mainboards (eg. octopus, hatch). Update the build rules to compile the
acpi_tables.c only if it is present. This will help to avoid adding
blank acpi_tables.c source file.

BUG=None
TEST=Build test with octopus and hatch without blank acpi_table.c file.
