add another conditional to nginx.spec.in to support fedora builds

[3van@…]

use_systemd already gets defined for builds on Fedora, so the only other change is to add it to the if block for RHEL 7:

--- ./a/rpm/SPECS/nginx.spec.in
+++ ./b/rpm/SPECS/nginx.spec.in
@@ -25,7 +25,7 @@
 BuildRequires: openssl-devel >= 1.0.1
 %endif
 
-%if 0%{?rhel} == 7
+%if 0%{?rhel} == 7 || 0{?fedora} >= 18
 %define _group System Environment/Daemons
 %define epoch 1
 Epoch: %{epoch}

Without this, builds fail in a sandboxed environment due to the missing OpenSSL dependency.

Oops. That should be "0%{?fedora}"... but you see what I'm saying.

We have no plans to build nginx packages for Fedora, so fedora specific changes in spec are redundant.

[3van@…]

It's an innocuous change that won't affect the releases you do spin, but makes it harder for everyone who uses your SRPMs to build packages for different platforms.

Besides, the %define for use_systemd already contains a conditional that specifically includes Fedora.
