graphics/argyllcms: Update to version 1.9.2, plus:
. add USES+=ssl;
. add dependency on graphics/png [*]

Argyll uses a bundled png library, configure shows:

Using system TIFF library
Using system JPEG library
Using Argyll PNG library
Using system Z library

Using system SSL library

Let the port not build the bundled but use the system PNG library.
