oeqa: Use cpio 2.13 as testcase

cpio 2.12 was released in 2015 and might have used older autotools
which could result in errors like

Bumping to 2.13 will help in matching the tool versions
A good change on top would be to run

aclocal -I .; autoheader; autoconf; automake --add-missing -c

before running configure step perhaps
