remove dotfile exclusion in copyDir

copyDir is used in configload/getter.go to copy previously downloaded modules instead of using the go-getter client every time. The go-getter client downloads dotfiles, but copyDir did not copy dotfiles, leading to inconsistent behaviour when reusing the same module source.
