merge revision(s) 190b017fc6c21ff7b61c2b5ece0294785e4a4ca2: [Backport #21703]

	[PATCH] Don't use non blocking pipes for RUBY_CRASH_REPORT

	[Bug #21703]

	RUBY_CRASH_REPORT does not work in some cases when shelling out on Linux.
	For example, given the following shell script dump.sh:

	    #!/usr/bin/env bash
	    cat > /tmp/crash

	And we see it fails like this:

	    $ RUBY_CRASH_REPORT="|dump.sh" ruby -rfiddle -e "Fiddle::Pointer.new(1, 10)[0]"
	    cat: -: Resource temporarily unavailable
