* after upgrade to 3.32.1, pygobject switch to build with meson, and
  default python option is python3, switch to python2

* default install dir get by python.install_sources and
python.get_install_dir is get from python's sysconfig info,
not like python3, for python2, the install dir include prefix of
recipe-sysroot-native dir, like "build/tmp-glibc/work/core2-32-wrs-linux/
python-pygobject/3.32.1-r0/recipe-sysroot-native/usr/lib/python2.7/site-packages"
add stagedir option for user to config correct install dir.
