package/libarchive: fix CVE-2022-36227

In libarchive 3.6.1, the software does not check for an error after
calling calloc function that can return with a NULL pointer if the
function fails, which leads to a resultant NULL pointer dereference.
NOTE: the discoverer cites this CWE-476 remark but third parties dispute
the code-execution impact: "In rare circumstances, when NULL is
equivalent to the 0x0 memory address and privileged code can access it,
then writing or reading memory is possible, which may lead to code
execution."
