Restore bash completions

05f9481 removed these as the shortest
path to preserving hermeticity of the build, but this solution was
overly aggressive. Restore the bash completions (and the config file) by
placing them in directories inside the package (rather than
system-wide).

Downstream distro packaging can move place the content of ./etc/ in
/etc/ and ./share/ in /usr/share/.
