PTAL.

Tested with 

$ ./glyco/glyco pack -o ~/glyco_wheels infra_libs
$ ./glyco/glyco install -i test_install ~/glyco_wheels/infra_libs-1.1.0-*

and verified that all expected packages and files are installed.

TBR'ing this - it won't break anything, but I need it to roll ts_mon in luci-py,
and share it with other teams.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2143493002/ by sergeyberezin@chromium.org.

The reason for reverting is: I think I rushed it - setup.py doesn't really work
without a deeper module structure. It needs to be next to infra_libs, not inside
it..
