android: Add support for Valgrind in debug variants

This patch allows bluetoothd to be run with Valgrind easily in debug
variants.

For userdebug and eng variants bluetoothd is renamed to bluetoothd-main
and bluetoothd acts a wrapper to launch it either with or without
Valgrind (this is decided by value of persist.sys.bluetooth.valgrind
property).
