Fix parallel test updates in CI; fbcode LIB_MODE=shared (#9553)

Summary:
* Fix LIB_MODE=shared for Meta-internal builds (use PIC libraries
appropriately)
* Fix gnu_parallel to recognize CircleCI and Travis builds as not
connected to a terminal (was previously relying on the
`| cat_ignore_eagain` stuff for Ubuntu 16). This problem could cause
timeouts that should be 10m to balloon to 5h.
