Hardcoded paths for aws config and credentials files

[browseman]

aws-saml does not follow the environment variables that awscli is supporting (link):

• AWS_CONFIG_FILE
• AWS_SHARED_CREDENTIALS_FILE

a simple patch will fix this:

diff --git a/awscli_saml/assume_role.py b/awscli_saml/assume_role.py
index 3d520a8..cb3a47b 100644
