[meta-oe][master][PATCH 1/2] p7zip: build and package lib7z.so needed for fastboot

["Nisha Parrakat" <nishaparrakat@gmail.com>]

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

| ../../../../CPP/7zip/Archive/Wim/WimHandler.cpp: In member function 'virtual LONG NArchive::NWim::CHandler::GetArchiveProperty(PROPID, PROPVARIANT*)':
| ../../../../CPP/7zip/Archive/Wim/WimHandler.cpp:308:11: error: use of an operand of type 'bool' in 'operator++' is forbidden in C++17
|   308 |           numMethods++;
|       |           ^~~~~~~~~~
