Subject: [PATCH RFT v9 5/8] selftests/clone3: Remove redundant flushes of
 output streams

Since there were widespread issues with output not being flushed the
kselftest framework was modified to explicitly set the output streams
unbuffered in commit 58e2847ad2e6 ("selftests: line buffer test
program's stdout") so there is no need to explicitly flush in the clone3
tests.
