Junio C Hamano 58eab6ff13 test-genzeros: avoid raw write(2) ...

This test helper feeds 256kB of data at once to a single invocation
of the write(2) system call, which may be too much for some
platforms.

Call our xwrite() wrapper that knows to honor MAX_IO_SIZE limit and
cope with short writes due to EINTR instead, and die a bit more
loudly by calling die_errno() when xwrite() indicates an error.
