Add --needed option to makepkg

Simply add the option to pass the --needed flag to pacman when using -i
with makepkg. When using makepkg in scripts, particularly for git
packages with the new version functions and not just a date, this can
save disk io and time instead of reinstalling.

This would mostly be useful with the --noconfirm option.
