initramfs_test: add fill_cpio() inject_ox parameter

fill_cpio() uses sprintf() to write out the in-memory cpio archive from
an array of struct initramfs_test_cpio. This change allows callers to
modify the cpio sprintf() format string so that future tests can
intentionally corrupt the header with "0x" and "0X" prefixed fields.
