elf: Change ldconfig auxcache magic number (bug 32231)

Browse Source 
In commit c628c22963 (elf: Remove
ldconfig kernel version check), the layout of auxcache entries
changed because the osversion field was removed from
struct aux_cache_file_entry.  However, AUX_CACHEMAGIC was not
changed, so existing files are still used, potentially leading
to unintended ldconfig behavior.  This commit changes AUX_CACHEMAGIC,
so that the file is regenerated.
