Subject: [PATCH 2/2] Loosen build time requirement on bash-completion

Distributions might avoid pulling bash-completion during build as it is
an optional feature and would only make sense at runtime anyway. Since
this setting is well-known across a given distribution, allow them to
provide the value and avoid the dependency.
