Move context and coroutine

Yocto upstream moved context and coroutine directly into BOOST_LIBS,
which means that they're not added back for our arm variant.

https://github.com/lgirdk/poky/commit/624262541605c476f5a0bd415b08d00379c15b00

This causes our build to fail with "cannot find -lboost_coroutine"
errors.  This should resolve it.

Tested:
Fixing CI break.  No functional testing done.
