[pgsql-pkg-yum] patch bug in 9.6 spec

Hi,

I was making a custom build with a patch for 9.6 and found this which
seems to be a bug in the spec file of postgresql 9.6.3 src.rpm package:

%patch6 -p1
%if 0%{?rhel} && 0%{?rhel} <= 5
%patch7 -p1
%endif

Compilation passed because I'm using rhel7, but that patch doesn't exist
in the spec file, so if someone would have tried to compile it on rhel5
it would have failed.

I didn't do much digging on when it got there, but it seems it would be
good to remove it.

Regards,
