package/cmake: ignore CVE-2016-10642

This is specific to the npm package that installs cmake, so isn't
relevant to Buildroot.
https://github.com/openembedded/openembedded-core/blob/14241ed09f9ed317045cf75a6d08416d3579bb8d/meta/recipes-devtools/cmake/cmake.inc

https://nvd.nist.gov/vuln/detail/CVE-2016-10642#vulnCurrentDescriptionTitle
 "cmake installs the cmake x86 linux binaries. cmake downloads
 binary resources over HTTP, which leaves it vulnerable to
 MITM attacks. It may be possible to cause remote code
 execution (RCE) by swapping out the requested binary with
 an attacker controlled binary if the attacker is on the
 network or positioned in between the user and the remote server."
