tools/testing/cxl: Disable "missing prototypes / declarations" warnings

Browse source 
Prevent warnings of the form:

tools/testing/cxl/test/mock.c:44:6: error: no previous prototype for
‘__wrap_is_acpi_device_node’ [-Werror=missing-prototypes]

tools/testing/cxl/test/mock.c:63:5: error: no previous prototype for
‘__wrap_acpi_table_parse_cedt’ [-Werror=missing-prototypes]

tools/testing/cxl/test/mock.c:81:13: error: no previous prototype for
‘__wrap_acpi_evaluate_integer’ [-Werror=missing-prototypes]

...by locally disabling some warnings.

It turns out that:

Commit 0fcb70851f ("Makefile.extrawarn: turn on missing-prototypes globally")

...in addition to expanding in-tree coverage, also impacts out-of-tree
module builds like those in tools/testing/cxl/.

Filter out the warning options on unit test code that does not effect
mainline builds.
