[PATCH 1/4] ndctl: switch to kernel versioning scheme

[Dan Williams]

Similar to perf, now that ndctl is part of the kernel source tree it
also shares the version number of the source tree. This is consistent
with the policy of not maintaining separate version numbers for drivers
within the kernel tree.

The version can be overridden by a local 'version' file, but now the
default version will no longer be hard coded. Instead, it is derived
from the kernel's 'kernelversion' Makefile target. The policy appending
'.git${abbrev_commit}', and optionally '.dirty', for off-label releases
is still the default when a git tree is available.
