[Docker] Add workarounds for two SYCL issues (#5143)

First issue is that SYCL runtime requires libOpenCL.so for correct functioning, which is typically built with the rest of compiler toolchain, but never gets deployed to installation directory.
Second issue is described in #5142, which breaks SYCL toolchain if it's installed to `/usr`.
Also add vim to the image for convenience of local work/debugging.
