Quote the list of patch files in case they have spaces in their paths (…

…#463)

The rapids cpm scripts fail when populating a dependency with patches if the build directory contains spaces in its path name. The reason is because the paths are not properly quoted in the cmake patch script generated from `command_template.cmake.in`.

This PR properly quotes the list of patch file names.
