BIND >= 9.18, jemalloc and EL7

[Ondřej Surý]

Hi Anand,

I think there's only a risk that ISC doesn't regularly test with older jemalloc versions,
so you might get a hit by a bug we are not aware of.

Upstream recommends upgrading to at least 5.1.0 and further releases (up to 5.3.0)
fixes some bugs introduced in 5.x releases, but it's ultimately your decision

It's little bit similar with libuv - you will be better running with latest upstream release,
but you can get away with older versions too.
