style(packaging): use long-form flags for less common options

Replace short flags with long-form equivalents for less obvious options:
  ln -sfn → --symbolic --force --no-dereference
  cp -L → --dereference
  grep -qE → --quiet --extended-regexp

Kept short form for universally known flags (mkdir -p, rm -rf,
chown -R, docker -v/-w/-e, etc.).
