qnew: omit meaningless and harmful putting subrepositories into target list

Before this patch, qnew puts updated subrepositories into target list
forcibly, if any of -I, -X or patterns are specified.

But this is meaningless and harmful, because:

  - putting subrepositories into target list doesn't affect the result
    of "localrepository.status()"

    "dirstate.status()" invoked via "localrepository.status()" always
    omits subrepositories from the result of it

  - any -I/-X opts and empty "pats" causes unexpected failure

    when any -I/-X opts are specified, "inclsubs" are always added to
    "pats", even if "pats" is empty.

    but this changes meaning of "pats" from "including all to be
    included" to "including only listed subrepositories"

    this may exclude ".hgsub" and cause unexpected exception raising
    ("can't commit subrepos without .hgsub" ).

  - qnew at other than repository root (with -I, -X or any patterns)
    causes unexpected failure

    "scmutil.match()" treats pattern without syntax type as 'relpath'
    type (= one rooted at cwd).

    but qnew puts subrepository paths rooted at the repository root,
    and it causes unexpected exception raising ("SUBREPO not under
    root ROOT" in "pathutil.canonpath()"), if "hg qnew" is executed at
    other than repository root with -I, -X or any patterns.

This patch omits meaningless and harmful putting subrepositories into
target list.

This omitting doesn't miss including updated subrepositories, because
subrepositories are specified to "scmutil.matchfiles()" directly, to
get "match" object for "localrepository.commit()".
