Fixed dotfile mv in pkg-build-deb picking up . and ..

The glob pattern `.*` matches `.` and `..`, causing spurious
warnings during tarball extraction. The `|| true` prevented the
script from failing, but the warnings are noisy and confusing.
Replaced with a loop that skips these special directory entries.
