Enable TAP tests of pg_receivewal for ZLIB on Windows, take three

This reverts commit 6a2c532.  fairywren and bowerbird failed those tests
because of incorrect versions of ZLIB linked to, causing errors like
SIGBREAKs that stopped buildfarm runs or EACCES failures when writing
compressed WAL segments.

Andrew Dunstan has done all the investigation here, so he deserves all
the credit for being able to enable those tests on Windows.
