Generalize fugu failure handling in run-libcore-tests.sh

Rename libcore_get_no_random_failures.txt to libcore_fugu_failures.txt
and add failures for memfd_create.

The command-line flag --no-getrandom continues to choose fugu failures
as fixing this requires coordination with buildbot scripts in
chrome-infra.

Bug: 146113753
Test: art/tools/run-libcore-tests.sh --mode=device --no-getrandom --verbose
