[yocto] [meta-mingw][PATCH] classes/toolchain-scripts-mingw32: Fix bad cmd flag

[Joshua Watt]

The command to properly set the exit code at the end of the toolchain
environment was using the correct flag delimiter '/', but the code to
coerce all the unix-style paths to windows paths was incorrectly
changing this to a '\'. This worked find in wines cmd, but on an actual
Windows host, this caused cmd to wait indefinitely. Fix this by
appending the command after the path separators are coerced.
