config: avoided an error with NGINX 1.17.0 and above. #79

Currently, building those modules with NGINX 1.17.0+ produces the following errors:

/path/to/echo-nginx-module/config: line 41: [: !=: unary operator expected
/path/to/srcache-nginx-module/config: line 30: [: !=: unary operator expected

Since the HTTP_POSTPONE variable is not defined. However, since the postpone filter is unconditionally enabled with NGINX 1.17.0 and above, we can simply skip this logic.
