Both term/ and hypr/ have scripts/ subdirectories and .stow-ignore files
that should not be stowed. Adding --ignore flags to stow commands in
entrypoint-test.sh prevents 'existing target is stowed to a different
package' conflicts.
Also remove @aur section from hypr/scripts/packages.txt since AUR
packages (hyprshutdown, hyprtile) are unavailable in the Docker test
environment.
All 93 smoke tests pass.
