[Buildroot] [git commit branch/2017.02.x] cmake: explicitly disable openssl support for host-cmake

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=a86d28d850583091bd1a9d137be12794b1102eae
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

host-cmake will optionally link with openssl for the embedded copy of
libarchive if available, leaking host dependencies and possibly causing
build issues in case of compatibility issues - E.G. the host-cmake version
we have in 2017.02.x doesn't build against openssl-1.1.0+:

https://github.com/libarchive/libarchive/issues/810

The openssl support in libarchive is unlikely to be needed, so explicitly
disable it.
