Temp fix for #4359 (#4573)

* make user wide integration not burn everything if LLVM is used as a toolset.
(e.g. cmake -G "VS" -TLLVM fails to even find compiler due to linker issues)
fixes #4359 but might have side effects for that toolset.
(e.g. not automatically adding dependencies)

* remove whitespaces

* [vcpkg-integrate] Conform to MSBuild conventions for comparisons
