[SYCL][Driver] Respect -nocudalib again after bad merge conflict resolution (#19216)

[fc26ef4][1] is a bad resolution
`--offloadlib` is a positive option to explicitly link offload device
libraries (usually on by default), while the option it replaced
(`-nogpulib`) was the negative option to disable linking them.
To behave correctly, we need to consider both positive and negative
options.

The test did not catch this because the filecheck CHECK-NOT directive
had a typo. Fix that as well.
