[Buildroot] [PATCH] support/scripts/check-uniq-files: ignore reinstalled packages

[John Keeping]

If a package is rebuilt, then any files it installs will be listed
multiple times in the file list and check-uniq-files will report that
these files are touched by more than one package even though it is the
same package listed multiple times.

Switch to storing the package names in a set so that each package can
only appear once.
