[PATCH] daq: fix build against the musl C library

[Sergio Prado <sergio.prado () e-labworks com>]

musl C library doesn't have any <sys/unistd.h>. Even on glibc,
<sys/unistd.h> is just doing #include <unistd.h>. So let's just
include <unistd.h>, and we can build daq against most common C
libraries (glibc, musl, uclibc-ng).
