Add support for tab completion in bash.

Summary:
From https://github.com/facebook/buck/pull/54.

When the bash_completion script is loaded, the user
can use the tab key to automatically complete the name of the
`buck command`, or if there are multiple commands beginning with
the same letter(s) suggest commands to use.

Test Plan:
Install the completion script:

  $ ./scripts/bash_completion

Suggestion of all available commands:

  $ buck
  audit build cache clean install project targets test uninstall

Suggestion of available commands with given starting letter:

  $ buck c
  cache clean

Completion of command with given starting letter

  $ buck b

("b" is auto-completed to "build")
