Fixes [YOCTO #10094]
For PROVIDES, I added information about how the do_package
task goes through PACKAGES and uses the FILES variable
corresponding to each package to assign files to the package.
For FILES, I added a blurb to the existing note how you can
find default values for the FILES* variables.
