[bug#50418] [PATCH core-updates-frozen 1/2] gnu: ocl-icd: Update project location.

[Sarah Morgensen]

The project seems to have permanently moved to Github, with no
distribution tarballs available, so update it.

* gnu/packages/opencl.scm (ocl-icd)[origin]: Retrieve source from Github
checkout instead of distribution tarballs.
[native-inputs]: Add 'autoconf', 'automake', and 'libtool'.
