xbps-bin(8): remove specified pkgs first in recursive case.

Browse Source 
Previously the specified pkg(s) were added at the tail of the
array, which was wrong. Add pkg(s) to the head of the array so that:

$ xbps-bin -Rp remove foo blah

foo and blah will be removed before any of its automatic dependecies.
