Fix build with Boost 1.89.0

Boost.System has been header-only since Boost 1.69 and will be dropping
the compatibility stub library in Boost 1.89 (boostorg/system@7a495bb).

Since the `system` component is only needed for Boost < 1.69, it can be
added to `BOOST_COMPONENTS` in the fallback find_package.
