Termix: fix nginx pid path and log paths on update (#) (#14419)

- Replace outdated 'pid /app/nginx' deletion with proper replacement
  of 'pid /tmp/nginx/nginx.pid;' -> 'pid /run/nginx.pid;'
- Add sed to redirect error_log from /tmp/nginx/ to /var/log/nginx/
- Add sed to redirect access_log from /tmp/nginx/ to /var/log/nginx/

Fixes: nginx: open() '/tmp/nginx/nginx.pid' failed (2: No such file or directory)
