package/acpica: rename HOST make variable override to ACPI_HOST
The HOST Makefile variable was renamed upstream to ACPI_HOST in [1].
This commit was first included in tag R02_14_20 (version 20200214).
See the change log [2].
This no longer correct use of HOST did not introduced any
compilation error, as the code uses constructs like:
#if defined(_LINUX) || defined(__linux__)
This patch change the variable name to follow upstream, just for
correctness.
