[Buildroot] [PATCH 2 of 6 v2] linux: don't take HEAD as default for git repositories

[Thomas De Schampheleire]

Specifying a floating tag like HEAD for a repository version is bad practice,
as it results in non-reproducible builds. This patch removes the default
assignment of HEAD as version when a custom git repository is used for the
Linux kernel.
