Quote cmake include path

[krzyzanowskim]

quote include path that helps if path contains eg. a space

@compnerd can you take a look?

I think that this could use a better commit message - it isn't immediately clear what it means. Normally the include path would refer to the CMAKE_MODULE_PATH which shouldn't require quoting if handled properly IIRC. This is in the generated config file and the quoting does matter here.

long story short: swift won't build if checkout to path with space

When building swift-project using build-script if fails randomly here and there, and this is one place where it fail to include cmake macros from a path with spaces.

@krzyzanowskim I think that you misunderstood me, I agree that this site should be quoted. I think that the "quote cmake include path" is a bit confusing is all. This is an include, but the quoting is applied to a parameter. The "CMake include path" is normally the CMAKE_MODULE_PATH, which is not being touched here and is confusing because you expect the diff to be different.

@swift-ci please test

I don't think that the commit message is worth keeping this open. Going to merge it.
