Subject: [PATCH] Use unistd.h not argp.h for all POSIX systems

getopt(3) is found in unistd.h on all POSIX systems and we make no use
of any of the GNU specific argp extensions. Include unistd.h directly to
allow building with musl on linux, whilst retaining compatibility with
glibc and other unices.
