Compilation failure with some libc

[hcodina]

Hi,

I had some compilation failures compiling with some libc such as musl.
Indeed, open() needs '#include <fcntl.h>' (Cf. man open)

To fix these compilation failures, Iadded this include in shd_dev_mem.c and shd_shm.c

Here is the related patch:

Subject: [PATCH 1/1] backend: Add missing include files

With some libc library (musl), shd_dev_mem.c and shd_shm.c do not
compile. Indeed, open() needs <fcntl.h> (Cf. man open).

This patch fixes the compilation issue adding this
include file.
