Maintenance: investigate removal of ctypes/libffi

[joel-wong-aws]

Description

Similar to aws-deadline/deadline-cloud#455, ctypes (libffi) is not longer required on Linux. The openjd-adaptor-runtime uses ctypes here and here. This means that versions of Linux without ctypes that import those modules may error.

Solution

Remove/replace ctypes and libffi in the two files linked above.
