[jss-vendor-prefixer] clip-path to -webkit-clip-path not working

[dcholth]

Expected behavior:
When the JSS encounters a clip-path on a webkit browser, it should put a '-webkit-clip-path:' in its place as well.

Describe the bug:
There is no change to the CSS. clip-path remains, but will not work with Webkit browsers such as safari.

The JSS
clipPath: 'inset(5px -1px -7px -1px)',

Should result in

'-webkit-clip-path:': 'inset(5px -1px -7px -1px)',

Codesandbox link:
Please create a codesandbox.io with the issue. Make it as minimal as possible as this will help us find the bug quicker.

Versions (please complete the following information):

• jss: clipPath: 'inset(5px -1px -7px -1px)',
• Browser [e.g. chrome, safari]: Safari & other webkit browsers.
• OS [e.g. Windows, macOS]: MacOS
  Feel free to add any additional versions which you may think are relevant to the bug.
