p7zip: build and package lib7z.so needed for fastboot

a) use option 7z to build the lib7z.so library
This is needed for android-tools for building fastboot
from android-tools

b) Packaged the lib7z.so and codec libraries as a part of this recipe
Fastboot RDepends on it lib7z.so

c) Fixed a C++17 forbidden error when lib7z.so is built

fixes the below error
