[Minios-devel] [UNIKRAFT/NEWLIB PATCH 4/5] Introduce <sys/unistd.h> for including both newlib and Unikraft definitions

[Costin Lupu <costin.lupu@xxxxxxxxx>]

The ukunistd internal lib defines mostly user related functions. Some of them
are not declared by newlib headers. For those ones we will use the <uk/user.h>
from the ukunistd lib.
