Extend aur support for -Qu

-Qu now has AUR support, it functions identically to `-Pu` and may replace
it in the futre.

Aditionally the pacman options `-n` and `-m` are also supported to
filter out native and non native packages. Other flags are not supported
currently.

Using any other `-Q` will fallback to Pacman.
