scripts/run-tests.sh: Use piglit's --ignore-missing

Recently we added a number of chamelium tests to the fast-feedback testlist.

Chemelium is build-optional - requires  `./configure --enable-chamelium`.

To mitigate issue with piglit exiting abruptly due to the (possibly)
missing test binaries, this makes it behave more gracefuly, considering
those as simply "notrun".
