boards/esp32c3-devkit/dropbear: enable SCHED_HAVE_PARENT

Dropbear's NSH PTY session reaps the child task with waitpid() and needs
CONFIG_SCHED_CHILD_STATUS, which depends on SCHED_HAVE_PARENT.  The
netutils/dropbear Kconfig now depends on SCHED_HAVE_PARENT and selects
SCHED_CHILD_STATUS (apache/nuttx-apps#3648); set SCHED_HAVE_PARENT here so
the dropbear defconfig stays consistent and the session no longer fails
with ECHILD after authentication.
