[cip-dev] [cip-kernel-sec 2/2] git_repo: add a check for the git_repo directory

[daniel.sangorrin@toshiba.co.jp (Daniel Sangorrin)]

Users are required to prepare a local git repository, by
default "../kernel", however there is no check at the
moment. Alternatively, we could also create a repository
for them (mkdir ../kernel; git init .) but that for
now let's just spit an error.
