lshal: flush at the end of Lshal::main().
The _exit() call in main() terminates the whole
process early without debug information properly
flushed. That is, the PipeRelay thread might have
finished but the written data is not flushed. Hence
properly flush at the end of Lshal::main
to ensure the debug data is properly written to
the output stream.
Test: manually with
adb shell lshal debug android.hardware.media.c2@1.2::IComponentStore/software
Test: manually with
adb bugreport
then check lshal-debug/android.hardware.media.c2@1.2__IComponentStore_software.txt
