Enable execution of complex shell commands via AdbServer

[rokuoku]

Sometimes we use AdbServer for triggering an execution of shell commands on the PC, however because CmdCommandPerformer::perform() uses Runtime::exec(String command) instead of Runtime::exec(String[] cmdarray) it is impossible to execute commands which contain whitespaces in their arguments, or commands which use output redirection or pipes.

It would be great if it was possible to execute commands via Runtime::exec(String[] cmdarray).
E.g. instead of command adbServer.performCmd("script.sh \"some text\"") which fails, execute command adbServer.performCmd(arrayOf("script.sh", "some text") which would execute correctly.
Another example is adbServer.performCmd(arrayOf("sh", "-c", "adb shell dumpsys deviceidle | grep mForceIdle")
