androiddeployqt: Add option to reinstall apk

Mainly for consistency with the old deployment method in Qt Creator,
androiddeployqt will uninstall any previously installed instances
of the application before installing it. This will remove any caches
or user data stored by the application. In many cases (most) it
would be more convenient to just overwrite the existing instance,
but keep all caches intact. This patch adds the --reinstall option,
symmetrical to --install. If enabled, the uninstall step will be
skipped.

[ChangeLog][androiddeployqt] Added option to install an APK without
uninstalling previous instances of same application.
