patch to fix the problem

In FreeBSD, the file vk_swiftshader_icd.json is not yet delivered with the
package. This is the case under Linux and Windows.

Without the file, errors will occur in some situations. For example, if
chromium is called with the --disable-gpu switch, the following errors are
reported.

These errors disappear with the file.
