oidc: ignore default AWS config

This commit makes the aws-cli-oidc tool ignore all the default AWS
configurations like env vars, credential files, and config files. This
fixes a circular dependency where the OIDC tool tries to analyze the
profile configrations which in turn rely on an already executed
(aws-cli-oidc) credential process.

Cache AWS tokens per role.

Before the commit, the AWS token was saved independently of a role. In
that case, if a user requests temporary credentials initially with a
role A, the obtained AWS token will be cached (so far so good). However,
if the user wants to obtains the credentials for some other role B and
the cached AWS token is still valid, this cached token for role A will
be reused. With this commit, the AWS token are cached per role.

Fix Makefile.

Release 83

Use keyring for caching.

The cached OIDC and AWS credentials are now stored in the keyring
(in an encrypted manner). This obviously improves the security
but also makes the code slightly simpler (we don't have to deal
with file I/O).

Print newline after JSON output.

Release 78

Replace graphic with ASCII.

While the png graphic was pretty and all, the ASCII art based graphic
has one big advatage: it makes the README self-contained. And this is
actually an issue as in the distributeion step (make dist) the README
is copied along the LICENSE and binary files. So we would need to
either copy the png file, too, or replace it with something that is
not depending on an external file. I decided for the latter option.
