build: Adapt to changes in Fedora packaging of bash-completion

Fedora 41 moved a CMake script for bash-completion from
bash-completion to bash-completion-devel package
<https://bugzilla.redhat.com/show_bug.cgi?id=1457164>. That broke
building dnf5.spec:

RPM build errors:

This adapts to the change.

Fixes: #1252
