lib: don't detach kernel driver by default

Browse Source 
Since this feature also disconnects running instances
of librtlsdr that claimed the device, it is now disabled
by default and can only be enabled at compile time.

To enable it when building with cmake:
cmake . -DDETACH_KERNEL_DRIVER=ON

To enable it when building with automake:
./configure --enable-driver-detach
