I agree with this change, but still it still leave a corner case broken.

For packages with _LICENSE_FILES defined and _REDISTRIBUTE = NO, if
local or override is used, the tarball is extracted but no license
files are copied.

This is because code that copies the files (a little below) is inside
an if chain that prevents any actions for local and overridden packages.

Probably the ifs should be reworked to be coherent in the two parts.
