The macros for STD*_FILENO are missing on windows. Add defines for them
to the DPDK-local unistd.h file.

Why is this needed?
There are 3 users of STD*_FILENO within DPDK:
* lib/eal/unix/eal_debug.c - not for Windows, obviously
* app/dumpcap - not for Windows, requires multi-process
* app/proc-info - not for Windows, requires multi-process
* examples/l2fwd-cat - not for Windows, requires <pqos.h>

This merged patch is now throwing errors about the missing defines on
Windows.

Thanks, I was searching some outdated source.

Currently, <rte_os_shim.h> contains at least `read()`, `write()`,
and `unlink()` which POSIX places in <unistd.h>.
I wonder whether all that stuff should be moved into EAL's <unistd.h>
or, on the opposite, <rte_os_shim.h> should consume all other shims.
But that would be a broader refactoring, so for the fix:
