Allow to open the device when using the App Sandbox on OSX
When running the App Sandbox, a system has no any temporary directories
which can be shared between applications (or, maybe, it is configurable
option):
* https://developer.apple.com/library/mac/documentation/Security/Conceptual/AppSandboxDesignGuide/AboutAppSandbox/AboutAppSandbox.html
In this case QSP::open() can not create a lock file that lead to fails
when opening.
Workaround it is to use the
QStandardPaths::writableLocation(QStandardPaths::TempLocation) for receiving
a temporal directory of application. Where the writableLocation() implicitly
uses the NSTemporaryDirectory function that is the recommended way
(see "The App Sandbox Container Directory") in here:
* https://developer.apple.com/library/mac/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW4
This will allow to open the serial port, but the locking feature will not
work properly.
