kexec -p fails on kernel versions of form x.y

"kexec -p" fails to load kernels with version of the form x.y instead of
x.y.z with an error message similar to "Unsupported utsname.release:
3.10-1-amd64". Code in kernel_version() also checks the wrong variable
name for error return value from strtoul() for "minor" and "patch", and
hence possibly missing a real error.

These changes fix both of these problems.
