Don't use /dev/null as test input file for the test for response file support. Busybox on Windows does provide POSIX utilities to the point of being able to build and test ffmpeg, but it doesn't provide full POSIX emulation like msys2 and cygwin do. Busybox utils do handle paths like /dev/null themselves. But when busybox invokes a native Windows executable (like the "$ar" tool in this test), it passes such a path as-is. Msys2 on the other hand rewrites unixy paths in command line parameters - even when prefixed; e.g. "@/dev/null" gets rewritten into "@nul". Instead of testing with a /dev/null input, test with a real temp file instead.
