update_engine: Block force update + install when not idle

Currently |CheckForUpdate()| and |CheckForInstall()| sets the values of
|is_install_| to false and true respectively. The change of the value
|is_install_| at the initial entry to these functions will cause the
checks and actions taken within |ProcessingDone()| to behave as it's not
intended to. This unwanted behavior occurs because |ProcessingDone()|
depends on |UpdateAttempter|'s member variable |is_install_|. Until
|ProcessingDone()| is called, the |is_install_| value needs to remain
the same.
