[autotest] swap python import order to support pip in moblab
In Moblab, the host's python modules located in
/usr/lib64/python2.7/site-packages is mounted to following folder inside
container: /usr/local/lib/python2.7/dist-packages/. The modules include
an old version of requests module, which is used in autotest
site-packages. For test, the module is only used in
dev_server/symbolicate_dump for requests.call and requests.codes.OK.
When pip is installed inside the container, it installs requests module
with version of 2.2.1 in /usr/lib/python2.7/dist-packages/. The version
is newer than the one used in autotest site-packages, but not the latest
either.
According to /usr/lib/python2.7/site.py, modules in /usr/local/lib are
imported before the ones in /usr/lib. That leads to pip to use the older
version of requests (0.11.2), and it will fail. On the other hand,
requests module 2.2.1 can't be installed in CrOS (refer to CL:265759),
and higher version of requests module can't work with pip.
The only fix to resolve this is to switch the import order, so modules
in /usr/lib can be imported before /usr/local/lib.
