contrib/buildsystems: fix Visual Studio Debug configuration

Even though Debug configuration builds, the resulting build is incorrect in a subtle way: it mixes up Debug and Release binaries, which in turn causes hard-to-predict bugs.

In my case, when git calls iconv library, iconv sets 'errno' and git then tests it, but in Debug and Release CRT those 'errno' are different memory locations.

This patch addresses 3 connected bugs: 1) Typo in '(Configuration)'. As a result, Debug configuration condition is always false and Release path is taken instead. 2) Regexp that replaced 'zlib.lib' with 'zlibd.lib' was only affecting the first occurrence. However, some projects have it listed twice. Previously this bug was hidden, because Debug path was never taken. I decided that avoiding double -lz in makefile is fragile and I'd better replace all occurrences instead. 3) In Debug, 'libcurl-d.lib' should be used instead of 'libcurl.lib'. Previously this bug was hidden, because Debug path was never taken.
