Fix: add some missing *_LIBRARY_DIRS to target_link_directories()

The following examples:
- umf_example_ipc_ipcapi_anon_fd
- umf_example_ipc_ipcapi_shm
- umf_example_custom_file_provider
require TBB and they have to know TBB_LIBRARY_DIRS.

The umf_example_dram_and_fsdax example requires HWLOC
and it has to know LIBHWLOC_LIBRARY_DIRS.
