dhcp: Fix REQUIRE(ctx->running) assertion triggered on SIGTERM/SIGINT
Closed a small window of time between the installation of graceful
shutdown signal handlers and application context startup, during which
the receipt of shutdown signal would cause a REQUIRE() assertion to
occur. Note this issue is only visible when compiling with
ENABLE_GENTLE_SHUTDOWN defined.
