cgpt_wrapper: Print error if execv() fails.
This shows an error message when cgpt.bin failed to run, with its
reason. Without this patch, "cgpt" would just fail and return -1 in
that case making it difficult to know the reason of the failure.
BUG=chrome-os-partner:36061
TEST=replaced this binary in storm recovery initramfs 6699.0.0 and it
shows the error message if cgpt.bin is not installed.
