Bug found by Herb. blkcnt_t st_ex_blksize is defined as a signed value. When it is
on a 32-bit system and defined as a long, then inside vfswrap_get_alloc_size()
we cast to a uint64_t. This sign-extends when converting to unsigned,
so if the high bit of st_ex_blksize is set we return insane values to clients.
