[PATCH] mmc-utils: Change version string to git hash

[Christian Loehle <CLoehle@hyperstone.com>]

Since mmc-utils versioning has always been 0.1 and changes are not
made frequently and formal releases do not happen, packaged versions
are just pulled from git anyway, using the git hash for version is
probably the best idea for now.
