Revert of Android Logging.java: Load native library only when needed (patchset #3 id:40001 of https://codereview.webrtc.org/2803203002/ )

Reason for revert:
Breaks C++ logs in Java apps.

Original issue's description:
> Android Logging.java: Load native library only when needed
>
> Logging.java currently always tries to load jingle_peerconnection_so in
> the static section, but some clients don't want to use it. This CL loads
> jingle_peerconnection_so only when a client requests it by calling one
> of:
>  * Logging.enableLogThreads
>  * Logging.enableLogTimeStamps
>  * Logging.enableTracing
>  * Logging.enableLogToDebugOutput
>
