falcon: Drop support for Python 3.4 (#774)

Remove unwanted support for Python versions <3.6.
This integration mistakenly lists Python 3.4 support, because it was
merged in
open-telemetry/opentelemetry-python#1039,
after the merge of
open-telemetry/opentelemetry-python#1099, so the
latter didn't consider `falcon`.

Python 3.4 is broken nevertheless, as this integration already includes
f-strings and other `opentelemetry` dependencies, which require Python 3.6.

Fixes #772.
