Harald Albers 5c93fb306b Bash completion: avoid 'compopt: command not found' errors on Mac OS ...

The shell builtin `compopt` is not available on the outdated bash
version 3.2.57 that ships with Mac OS.
It is used in Docker's bash completion to suppress trailing spaces
in advanced completions of hash map options, e.g. `--log-opt`.

If `compopt` is not available, the new behavior is to do nothing,
i.e. the user will have to delete the additional space.
