docker-io.spec patch

Description of problem:
Current docker-io.rpm is not debuggable at all.
With the patch below the debugging gets significantly improved.
Further fixes will be needed.

Version-Release number of selected component (if applicable):

How reproducible:
Always.

Steps to Reproduce:
gdb -ex 'catch fork' -ex r -ex 'thread apply all bt' --args docker -d

Additional info:
There was Bug 1017186 Comment 3 but I do not see it would not be working:
# This also adds -w, to disable building with debugging in the executable which
isn't working with debuginfo anyway.
