subrepo: warn when adding already tracked files in gitsubrepo

This follows normal Mercurial rules, and the message is lifted from
workingctx.add().  The file is printed with abs() to be consistent with how it
is printed in workingctx, even though that is inconsistent with how added files
are printed in verbose mode.  Further, the 'already tracked' notifications come
after all of the files that are added are printed, like in Mercurial.

As a side effect, we now have the reject list to return to the caller, so that
'hg add' exits with the proper code.  It looks like an abort occurs if git fails
to add the file.  Prior to touching 'snake.python' in the test, this was the
result of attempting to add the file after a 'git rm':

    fatal: pathspec 'snake.python' did not match any files
    abort: git add error 128 in s (in subrepo s)

I'm not sure what happens when git is a deep subrepo, but the 'in s' and
'in subrepo s' from @annotatesubrepoerror are redundant here.  Maybe we should
stat the files before invoking git to catch this case and print out the prettier
hg message?  The other thing missing from workingctx.add() is the call to
scmutil.checkportable(), but that would need to borrow the parent's ui object.
