ybin --bootonce doesn't work, for a couple of reasons:

1) It inverts the logic of a test to see if nvram is available, and
2) It assumes the output of 'nvsetenv VARNAME' will be 'VARNAME=VALUE', rather
than just 'VALUE' (as it is when using the "nvram" utility).

The attached patch fixes these problems and makes --bootonce work as expected.

Hi Roman-

Unfortunately, I no longer have access to any PPC hardware to verify
your fix, but examining the patch, it looks okay to me.

Paul-

Assuming you (or someone else on the list) can verify the
functionality of Roman's patch, I think this should be committed.
