Include <poll.h> instead of <sys/poll.h>

According to the Single Unix Specification, the poll() function has been
declared in the <poll.h> header file. This makes the SCST code compatible
with the musl C library. See also https://en.wikipedia.org/wiki/Musl. See
also https://github.com/bvanassche/scst/issues/23.
