TestUseSourceCache attempts to write to a build artifact copied from the source
tree, and asserts the write succeeded. If the source tree is read only, the
copy will also be read only, causing it to fail. When producing the build
artifact, ensure that it is writable.
I use `chmod` as a build step to do this, but I believe that is linuxish-only
thing, so I excluded this extra command for Windows.
