[Minios-devel] [UNIKRAFT/NEWLIB PATCH] Update fcntl() related definitions

[Costin Lupu <costin.lupu@xxxxxxxxx>]

Since we are using the fcntl() implementation in vfscore, we don't use newlib's
any more. This patch also adds some flags that are needed by fcntl() and that
were copied from musl, just like the previous ones from fcntl.h.
