tools/libxc: Implement writev_exact() in the same style as write_exact()

This implementation of writev_exact() will cope with an iovcnt greater than
IOV_MAX because glibc will actually let this work anyway, and it is very
useful not to have to work about this in the caller of writev_exact().  The
caller is still required to ensure that the sum of iov_len's doesn't overflow
a ssize_t.
