  [flang][runtime] Correct RANDOM_INIT seed generation (#106250)

The initial seed was generated from a bitwise AND ("&") of two
clock-generated values, instead of an XOR or (best) a truncated integer
multiplication. Maybe I mistyped a shift-7 instead of a shift-6 or
shift-8 when I wrote that line, but it was most likely just stupidity.

Fixes https://github.com/llvm/llvm-project/issues/106221.
