Work around a hang in fork(2) on FreeBSD
See bug https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271490
On FreeBSDk, it's possible for fork(2) in a multithreaded process to
hang because of a bug in the lock handling of the dynamic linker. This
is now fixed on FreeBSD master, but it would be good if we could work
around it for Ruby CI which is running 13.1.
Setting LD_BIND_NOW seems to work around the problem (probably because
the dynamic linker doesn't then need to resolve anything through the PLT
when it's first called).
