add support for the old naming libs convention on windows (ssleay32.lib and libeay32.lib)

Hi,

Summary of Changes:

According to the postgresql-17 requirements
https://www.postgresql.org/docs/17/install-requirements.html
the minimum required version of openssl is 1.0.2.
In that version, the naming convention on windows is still
ssleay32.[lib|dll] and
libeay32.[lib|dll] instead of libssl.[lib|dll] and libcrypto.[lib|dll].
It changed in version 1.1.0
https://github.com/openssl/openssl/issues/10332#issuecomment-549027653
Thus there is a bug in meson.build as it only supports libssl.lib and
libcrypto.lib,
hence a simple patch that fixes the issue and supports both conventions.

I also submitted a pull request on GitHub, which can be found here:
https://github.com/postgres/postgres/pull/188
There are two simple changes in the meson.build file.

Reason for Changes:

Add support for the old naming libs convention on windows (ssleay32.lib and
libeay32.lib).

Testing:

The patch has been tested against postgres-17 and openssl v1.0.2 in our
environment on various platforms (lnx, win, ...)
