add: fix subrepo recursion for explicit path handling

add: fix subrepo recursion for explicit path handling

When support for handling explicit paths in subrepos was added to the add
command (9e99d2bbb1b1), subrepo recursion wasn't taken into account.  This
change adds an explicitonly argument to cmdutil.add to allow controlling which
levels of recursion should include only explicit paths versus all matched
paths.
