`pwntools.adb.wait_for_device()` breaks when `ro.build.date` has non-standard value

[mr6r4y]

Some devices return strange string in ro.build.date property:

$ adb shell getprop ro.build.date
2017年 11月 14日 星期二 09:55:07 CST

That breaks dateutil's parser and when using pwnlib.adb.wait_for_device() the following breaks:

>>> adb.wait_for_device()

I tested my Xiaomi and it didn't print any chinese characters. It seems that the ro.build.date field depends on the system which built your android system. I notice that ro.build.date.utc is a integer, that should be safe and easy to process compared to ro.build.date.
