cpp_stl/{clang3.4,gcc4.8}: build latest Boost 1.84 from source

See
kaitai-io/kaitai_struct_tests#105 (comment)
- Boost 1.54 is too old for our purposes. Fortunately, it's quite easy
to build Boost from source (according to the documentation at
https://www.boost.org/doc/libs/1_84_0/more/getting_started/unix-variants.html)
and it doesn't take long if we only need to build the Boost.Test
library. It's much faster than building CMake which is already being
done (on my machine, downloading and building Boost.Test takes 2
minutes, whereas building CMake takes 21 minutes).
