[SYCL][XPTI] Fix libraries installation path (#2286) (#5288)

Align installation rules for XPTI libraries with the ones used for
OpenCL ICD loader to avoid installing to lib64 directory.

That causes missing of the libraries during E2E testing:
 - llvm_test_suite_sycl/xpti_buffer* tests are impacted.
