package_rpm.bbclass: support packaging of symlinks to directories
os.walk() returns symlinks to directories in the "dirs" lists, but then never
enters them by default. As a result, the old code applied neither the
directory handling (because that is active once a directory gets entered) nor
the file handling, and thus never packaged such symlinks.
The fix is simple: find such special directory entries and move them to the
"files" list. However, one has to be careful about the undefined behavior of
modifying a list while iterating over it.
This fix was required for packaging a modified base-files that created
symlinks into /usr for /sbin /lib and /sbin.
