trusty: keymaster: Remove legacy support
Library based HALs have been deprecated for several years now, and
Keymaster 2 based testing is woefully out of date compared to running
VTS against the modern 3.0 and 4.0 implementations.
Purging these modules and their resulting dependencies will make it
easier for the central system/keymaster repository to move forwards.

-# Local unit test Makefile
-#
-# This makefile builds and runs the trusty_keymaster unit tests locally on the development
-# machine, not on an Android device.
-#
-# To build and run these tests, one pre-requisite must be manually installed: BoringSSL.
-# This Makefile expects to find BoringSSL in a directory adjacent to $ANDROID_BUILD_TOP.
-# To get and build it, first install the Ninja build tool (e.g. apt-get install
-# ninja-build), then do:
-#
-# cd $ANDROID_BUILD_TOP/..
-# git clone https://boringssl.googlesource.com/boringssl
-# cd boringssl
-# mdkir build
-# cd build
-# cmake -GNinja ..
-# ninja
-#
-# Then return to $ANDROID_BUILD_TOP/system/keymaster and run "make".
