Add valgrind suppression file

- valgrind is not happy about us now processing /proc/self/auxv on Linux,
  this can be used to suppress the false positives when running
  rpm under valgrind. At least until a better solution is found or
  valgrind is taught to treat /proc/self/auxv specially (see
  https://bugs.kde.org/show_bug.cgi?id=253519)
