CVE-2020-27350: debfile: integer overflow: Limit control size to 64 MiB
Like the code in arfile.cc, MemControlExtract also has buffer
overflows, in code allocating memory for parsing control files.
Specify an upper limit of 64 MiB for control files to both protect
against the Size overflowing (we allocate Size + 2 bytes), and
protect a bit against control files consisting only of zeroes.
