Make keymaster more self contained

Keymaster uses UniquePtr, a reimplementation of std::unique_ptr offered
by the Android framework. As keymaster becomes part of the trebbelized
HAL, it must build with the vndk. As such it must not use framework
headers. An attempt to replace UniquePtr with std::unique_ptr, which
is available in the vndk, failed because keymaster, i.e., parts thereof,
must also build and run in the Trusty environment which does not have
a full C++ STL.

This patch makes keymaster more self contained. To that end the
following was done by this patch.

 * Install a copy of UniquePtr.h in include/keymaster.
 * Add a tiny subset of STL symbols to keymaster.
 * Reorganize linking units and
 * build parts of keymaster with stl: "none".

libkeymaster1 was split into libkeymaster_portable and libkeymaster.
The former comprises all compilation units that are included
in the keymaster TA (trusted app) and must run on Trusty.
This library is built with the option stl: "none" to raise
compilation errors as soon as someone tries to use STL features.
A tiny subset of STL symbols, which are also available in Trusty
is weakly defined in keymaster_stl.cpp.
The latter library comprises some other functionality that is
used by the softkeymasterdevice on Android and may use the STL.
