t5300, t5302, t5303: Do not use /dev/zero
We do not have /dev/zero on Windows. This replaces it by data generated with printf, perl, or echo. Most of the cases do not depend on that the data is a stream of zero bytes, so we use something printable; nor is an unlimited stream of data needed, so we produce only as many bytes as the test cases need.
