Fix dotprod detection This fixes the detection of dotprod capable CPUs. Previously it looked for the `dotprod` flag, but this does not exist (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm64/kernel/cpuinfo.c#n50). The correct flag that specifies the dotprod capability is the `asimddp` flag. fixes #4931 closes https://github.com/official-stockfish/Stockfish/pull/4991 No functional change
