IRSL: Add paths for Intel oneAPI compilers on Linux

Added the location of the oneAPI runtime libraries. They are stored in a slightly different place with oneAPI than they used to be in Parallel Studio.

The list of libraries will also need to be revised in a further step, but I didn't want to bite off more than I could chew.

P.S. Note that the previous path is correct for PSXE 2019 for instance. I'm just adding that here, because at first I thought I found a bug in the code. But instead it's just that the code was not updated for oneAPI yet.

Backport: release
