apparmor: docker-default: Include base abstraction

Encountered problems on 14.04 relating to signals between container
processes being blocked by apparmor. The base abstraction contains
appropriate rules to allow this communication.

Fix edge case in bind mount absolute path detection

`filepath.Abs` does more than just `filepath.IsAbs` - namely, `filepath.Clean`, which resolves things like `.../.` or `.../../...`, and causes even an absolute path like `/some/path/../absolute` to fail (or, in my case, `/path/to/docker/.`)

Just using `filepath.IsAbs` directly is a much cheaper check, too. :)

Fix a few minor man formatting consistency issues

Some flags ended with a colon, some didn't.  For man pages, the prevailing normal practice is not to end the flags lines with colons.

Update RELEASE_BUNDLES to include integration tests

Previously, running just "hack/release.sh" only ran the unit tests.  This updates that to run the unit tests, then the integration tests, then build the binaries, then run the cli integration tests (so we're literally testing the binary we're about to release, which is super freaking cool IMO <3).
