[PATCH 1/3] libapi: Add missing header with NAME_MAX define to io_dir.h

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Most systems get this indirectly, but some odd cases (some musl libc
systems) can't find it, so just add the header where NAME_MAX is defined
to avoid that.
