Core: fix a memory leak in Nginx signaller processes.
A memory pool created by the 'main()' function is not destroyed when
Nginx is run as a signaller process.
Signaller processes are inherently short-lived so this does not cause
any noticeable memory overhead. However, memory leaks detectors such as
AddressSanitizer and Valgrind report this issue and cause Nginx to exit
with a failure core.
