tools/testing/cxl: Don't wrap cxl_core's own exported symbols

Building cxl_test with LLVM=1 (ld.lld) fails in modpost:

"""
  cxl_core: .export_symbol section references '__wrap_...', but it
  does not seem to be an export symbol
"""

cxl_test --wraps 6 symbols that cxl_core both defines and exports.
GNU ld only wraps undefined references, but ld.lld also redirects
references to defined symbols, so cxl_core's own EXPORT_SYMBOL entries
get rewritten to __wrap_* and modpost rejects them.

cxl_core never calls these symbols, so wrap them only in the caller
modules via LDFLAGS_<module>.o instead of the global ldflags-y.
