Disable getDebugInfo address leak for production builds.
On production builds debugfs won't be available, so lshal cannot
infer binder relationships anyway. The address leak on production
builds also expose a security hole for address space attacks.
Added a build-time flag to disable the address leak on user builds.
The address will still be exposed for eng and userdebug builds so
that lshal can work properly.
Bug: 34899586
Test: lshal still works
