nixos/tests: add test for nginx temp directories removal

Browse source 
The default temp directories for nginx must not be removed by
systemd-tmpfiles-clean.service. This test lowers the age parameter for /tmp and
triggers a cleanup that would normally only occur after 10 days of nginx
inactivity. After that, the functionality of nginx that requires a temporary
directory is tested again.
