popen() now returns a fopencookie-backed FILE* whose fileno() yields the
cookie pointer rather than a real descriptor, so poll() silently ignores
the negative fd and the relay loop blocks forever waiting for command
completion. See https://github.com/apache/nuttx-apps/pull/3511
Use dpopen()/dpclose() to obtain the raw bidirectional socket descriptor
directly, restoring the EOF/POLLHUP command-completion signal.

When using AF_RPMSG (-r option), rexecd was setting the rp_name
to the raw port number, while rexec was using htons(port). This
caused a mismatch where rexec couldn't connect to rexecd.
This commit fixes the issue by applying htons() to REXECD_PORT
when setting rp_name in the AF_RPMSG case, making it consistent
with the rexec client implementation.
