mq: omit ".hgsubstate" from qnew/qrefresh target list for consistent node hash

Before this patch, even if specified file patterns and -I/-X options
cause listing ".hgsubstate" up in the target list, qnew/qrefresh put
".hgsubstate" into the target list individually and forcibly.

This changes how many times ".hgsubstate" appear in the target list
according to run-time conditions, and causes inconsistent node hash,
even though revision content is same, because node hash calculation
uses the specified target list directly (without duplication check or
so).

This patch always omits ".hgsubstate" from qnew/qrefresh target list
for consistent node hash.

This omitting doesn't miss including ".hgsubstate" changes, because:

  - "localrepository.commit()" puts ".hgsubstate" into the target list
    for "commitctx()" forcibly if needed

  - "mq.putsubstate2changes()" puts ".hgsubstate" into the target list
    for "patch.diff()" if it is not yet listed up
