utils/size-stats-compare: add package name in detail output

Browse Source 
size-stats-compare gives an overview of the size increase/decrease between
two cases, based on packages-file-list.txt. The 'detail' mode gives info per
file, otherwise per package.

But sometimes, you want the detailed per-file info, but only for a specific
package. Since the detailed output no longer lists the package name, you
cannot simply grep for it. A workaround was to filter the input
packages-file-list.txt's first, and then pass these filtered versions to
size-stats-compare.

Make this easier by adding the package name next to the filename in detailed
output. This allows grep'ing normally.
For example:

  $ utils/size-stats-compare orig new  -t 100 -d | grep ebtables
