        src/tests/lib/libc/gen: t_arc4random.c

Log Message:
t_arc4random: Fix test to guarantee global state initialization.

Previously, if pthread_atfork failed, arc4random_global_buf would
fail to initialize the global state as intended.  (There are separate
tests for intentional failure of global state initialization.)  It is
unlikely for pthread_atfork to fail, but with RLIMIT_AS cranked down
to zero, it may.  To ensure that the global state is successfully
initialized for the tests that are trying to exercise it, call
arc4random from another thread first before forcing failure of the
local state initialization.

PR lib/59117: arc4random has some failure modes it shouldn't
