tools/fetch-distro: support the case where the sources are in a subdirectory

Browse Source 
If the GIT_SUBDIR environment variable is set, do not checkout the full sources
of the git repository, but perform a sparse checkout of the directory containing
the package. In this case, check only the commit history in this subdirectory.
