build: Set up cmake 'install' build target

The 'install' build target creates a self-contained (deployable) sparkd
package. It copies the sparkd executable and its dependencies into a
single directory (no symlinks), which can then be copied/deployed to
another machine.

Run `cmake --build . --target install` to install sparkd in the
directory defined by the CMAKE_INSTALL_PREFIX variable.
