Unnecessary root warning

[exuvo]

The "fix" for #13 in ec38666 is silly. There is no need to print a warning message about 'building as root' and delay for 2 secs when installing normal packages or querying the local database.
That warning is only relevant for when actually building packages and most operations already have a 'wait for keypress' before actually proceeding.

I request a revert of ec38666

The delay is extremely annoying and should be removed.

pacman 4.2 doesn't support --asroot option anymore, so yes, we must do something about this warning

The warning was removed, but --asroot had been dropped -> #67
