FreeBSD: make rfork() fail more gracefully

rfork() is barely used in base FreeBSD. The main use
is in posix_spawn(). If rfork() fails with EINVAL
then it falls back to using vfork(). This is preferable
to Valgrind bombing.

ksh93 uses posix_spawn. I tested bash and csh and they had
no problems.

Also add 'hello world" smoke tests for bash csh and ksh
