'primitive-fork' closes and recreates the current thread's 'sleep_pipe'.
Partly fixes <https://bugs.gnu.org/41948>.
Previously, the child process could end up using the same 'sleep_pipe'
as its parent, leading to a race condition handling signals.
* libguile/posix.c (do_fork): New function.
(scm_fork): Call 'do_fork' via 'scm_without_guile'.
* test-suite/standalone/test-signal-fork: New test.
* test-suite/standalone/Makefile.am (check_SCRIPTS, TESTS): Add it.
