pgxs.mk: remove unreachable rule for deleting regress.def.

We never create regress.def, and if we did this code would fail to
delete it, because "win" is not the correct PORTNAME for Windows.

This thinko seems to have originated in commit 7a6b562fd from 1999,
although it got moved around multiple times since then.
