[Buildroot] [PATCH 6/9] apr: various improvements

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

This commit:
 * Adds licensing informations
 * Ensures the apr-1-config script gets fixed appropriately
 * Remove the usr/build-1/ directory from the target, since it is only
   used during the compilation of packages that rely on APR.
 * Fix up a few paths in usr/build-1/ so that the compilation of
   apr-util works properly on top of this apr package.
