numeric-owner: print big UID/GID correctly

* src/list.c (simple_print_header): Do not parse ustar header
for UID/GID again (tar_stat_info has already been correctly
filled with respect to possible uid/gid extended headers).
* tests/numeric.at: New testcase for --numeric-owner option.
* tests/Makefile.am: Add new testcase.
* tests/testsuite.at: Likewise.
