Allow contrib/file_fdw to read from a program, like COPY FROM PROGRAM.

Allow contrib/file_fdw to read from a program, like COPY FROM PROGRAM. This patch just exposes COPY's FROM PROGRAM option in contrib/file_fdw. There don't seem to be any security issues with that that are any worse than what already exist with file_fdw and COPY; as in the existing cases, only superusers are allowed to control what gets executed. A regression test case might be nice here, but choosing a 100% portable command to run is hard. (We haven't got a test for COPY FROM PROGRAM itself, either.)
