upload: report names of uncommitted files

When there are uncommitted files in the tree, 'repo upload' stops to
ask if it is OK to continue, but does not report the actual names of
uncommitted files.

This patch adds plumbing to have the outstanding file names reported
if desired.

BUG=None
TEST=verified that 'repo upload' properly operates with the following
    conditions present in the tree:
    . file(s) modified locally
    . file(s) added to index, but not committed
    . files not known to git
    . no modified files (the upload proceeds as expected)
