Add support of arm for doctor

This is half of the fix to make the doctor suite run on arm.
The other half is at https://gerrit.opnfv.org/gerrit/#/c/20369/
In this fix I set an enviroment variable, to be used by
the doctor suite when ran with functest. The variable is set only
when present in config_functest.yaml, which we use as a custom file
when running functest on arm.
