scripts: llvm: Disable Picolibc FP exception and rounding tests

LLVM compiler-rt does not currently support exceptions and rounding modes for computations on the types that are emulated in software. For more details, refer to the GitHub issue zephyrproject-rtos#838. Revert this commit when this issue is fixed in the compiler-rt. Signed-off-by: Stephanos Ioannidis <[email protected]>
