package/syslog-ng: update patch that fixes --with-net-snmp

The final solution accepted upstream differs from the local patch applied
earlier in Buildroot (commit 4ff6e5239240a4e1bdf73c41d6e9bff9473ec62c).

Update the local code accordingly.

 The option '--with-net-snmp' did not work, because later checks were using
 the variable '$with_netsnmp' rather than '$with_net_snmp'.
@@ -10,32 +10,40 @@ There are two possible solutions:
 - make the option '--with-netsnmp'
 - change the internal variables
 
-Taking into account that latest upstream has moved away from autotools and
-towards cmake, we opt for the first option that has the least amount of
-changes.
+Opt for the second option so the user-visible options remain the same.
