pgsql: Handle spaces in OpenSSL install location for MSVC

Handle spaces in OpenSSL install location for MSVC

First, make sure that the .exe name is quoted when trying to get the
version number. Also, don't quote the lib name for using in the project
files if it's already been quoted. This second change applies to all
libraries, not just OpenSSL.

This has clearly been broken forever, so backpatch to all live branches.

Branch
------
REL9_4_STABLE
