[OE-core] [PATCH 6/9] scripts: add buildhistory-tag script

[Paul Eggleton]

This trivial script determines BUILDHISTORY_DIR using bitbake and then
passes the command line options to "git tag" on the buildhistory
repository. This is useful for setting a tag before making some changes;
even if the build takes a number of executions of bitbake (resulting in
multiple commits to the buildhistory repository) you can still do the
overall comparison easily.

Suggested by Ross Burton <ross.burton at intel.com>.
