[lldb][test] Disable riscv32 disassembly filter test on Windows
Added by https://github.com/llvm/llvm-project/pull/145793
Failing on our Windows on Arm bot:
https://github.com/llvm/llvm-project/pull/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.
