In 1.91.0 (4981f3087a30) boost-system became a header-only "modular"
library with no separate shared object, and was therefore dropped from
BOOST_LIBS. As a side effect its CMake package config is no longer
installed: the top-level b2 install target only ships configs for the
libraries selected via --with-<library>, and 'system' can no longer be
named there (b2 errors out with "wrong library name 'system'").

Downstream software that does find_package(Boost COMPONENTS system) then
fails to configure and has to be patched.

Install the modular 'libs/system//install' target explicitly from
do_install so that lib/cmake/boost_system-<ver>/ is shipped again in the
-dev package. The target is header-only, so no library is built or
packaged; only the CMake config (and already-present headers) are added.

Verified with a from-scratch build: boost_system-config.cmake is packaged
into boost-dev and find_package(Boost REQUIRED COMPONENTS system)
succeeds against the installed tree again.
