[OE-core] [PATCH v2 1/2] boost: ensure boost to remain an empty metapackage

[Lukas Bulwahn]

To ensure that boost remains an empty metapackage after version
updates, we explicitly require boost files to be empty. If new
libraries exist after a version update of the boost recipe,
bitbake will emit a warning at the do_package task. For example,
at the version update from 1.58.0 to 1.59.0, the new timer
library is indicated with:

WARNING: QA Issue: boost: Files/directories were installed but not shipped in any package:
  /usr/lib/libboost_timer.so.1.59.0
Please set FILES such that these items are packaged. Alternatively if they are unneeded, avoid installing them or delete them within do_install.
boost: 1 installed and not shipped files. [installed-vs-shipped]

Ross Burton suggested this improvement on the openembedded-core
mailing list during review of the boost recipe version update [1].
