cfg80211: ship certificates as hex files
Not only does this remove the need for the hexdump code in most normal kernel builds (still there for the extra directory), but it also removes the need to ship binary files, which apparently is somewhat problematic, as Randy reported. While at it, also add the generated files to clean-files. Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
