bump(6644d4): spf13/cobra: support bash completion for aliases

Fixes kubernetes/kubectl#120

`spf13/cobra` was recently bumped in kubernetes/kubernetes#60530. The changes between then and now are:

- Fix generated bash completion for Bash 3 (OSX): spf13/cobra@fd32f09 
- Try out CircleCI: spf13/cobra@be77323 (but we don't vendor this in anyway)
-  Do not add a space after a single flag completion: spf13/cobra@1a618fb
- Bash completion aliases: spf13/cobra@a1e4933 (the commit that fixes kubernetes/kubectl#120)
-  Prefix bash functions with root command name: spf13/cobra@6644d46 (the commit that completely fixes kubernetes/kubernetes#60517)

No license changes.
