Fixup win32 paths for moved bin/tests/system/resolve
When resolve.c was moved from lib/samples to bin/tests/system, the resolve.vcxproj.in would still contain old paths to the directory root. This commit adds one more ..\ to match the directory depth.
Additionally, fixup the path in BINDInstall.vcxproj.in to be bin/tests/system and not bin/tests/samples.
