Automerge: [lldb][test] Disable riscv32 disassembly filter test on Windows

Added by llvm/llvm-project#145793

Failing on our Windows on Arm bot:
llvm/llvm-project#145793

Shebang lines don't work on Windows and we can't pass "python script_name"
to the "fdis set" commadn because of the way arguments are parsed currently.

I can fix that but that needs review, disable the test for now.
