builder - Source vs distfiles priority

[Jakub Bogusz]

It seems that current (HEAD) builder tries to fetch source from SourceX
URL (mirror) first... but distfiles (or its mirror) should have higher
priority.
Unless -nd (or some equivalent upgrade option) is given.

Same for sources/patches with URLs and NoSource*-md5, for which CVS
should have higher priority than Source/Patch URL.

Or at least some configuration option should exist to select preferred
source of files.
