boost: Copy cmake in InstallDev step

Copy the cmake directory in the InstallDev step.
I am currently trying out actual host build for boost i.e. compiling
boost libaries for host tools. When I do that, that step installs the
boost cmake files in staging_dir/host.

This breaks other packages that use cmake to compile and use boost as a
dependency. This is because, their compilation step now begins using
staging_dir/host version of Boost, rather than the target version of
boost. Cmake gives priority to cmake version of Boost config, over
finding boost headers manually.

This change resolves that problem by installing the BoostConfig.cmake
file in staging_dir/<target> as well.

Compile tested: nbg6817
