make installcheck on non-default ports

I was trying to set up my dev box for multiple simultaneous Postgres
installs (7.3 stable, 7.4 stable, cvs head) and discovered that
`make installcheck` did not honor the default port assigned at configure
time. I view this as a bug.

The attached resolves the issue for all three versions.

Any objections to me applying this to cvs head? What about 7.3 and 7.4
stable branches?

Thanks,

Joe
