package/boost: remove dependencies on Boost.System

Browse Source 
Boost.System is a header only library since Boost 1.69.0 [0].

A Stub Library remained for backward compatibility. This
mainly affects CMake Packages that use FindPackage and
explicitly list 'system'.

For Boost internal modules this is not the case so remove this
dependency.

Buildroot packages should select BR2_PACKAGE_BOOST_SYSTEM explicitly
if needed and not rely on a proxy dependency from other boost packages.
