lscpu: don't assume filesystem supports d_type when searching for NUMA nodes

Not all file systems support the d_type field and simply checking for
d_type == DT_DIR in is_node_dirent would cause the test suite to fail
if run on (for example) XFS.

The simple fix is to check for DT_DIR or DT_UNKNOWN in is_node_dirent.
