import: change "editform" to distinguish merge commits from other (--bypass)

"editform" argument for "getcommiteditor" is decided according to the
format below:

  COMMAND[.ROUTE]

  - COMMAND: name of command
  - ROUTE: name of route, if there are two or more routes in COMMAND

This patch uses "bypass.normal" and "bypass.merge" as ROUTE of
"editform" instead of "bypass", to distinguish merge commits from
other in "hg import --bypass" case.

Unlike other patches in this series, this patch uses "editor.sh"
instead of "checkeditform.sh" for the name of the script to check
"HGEDITFORM", because it has to do more than checking "HGEDITFORM".
