    Fix target remote pipe command for MinGW
    
    The cced7cacecad104fff0 ("gdb: preserve `|` in connection details string")
    commit added '|' detection and removal to ser-pipe.c, but missed to add it
    to ser-mingw.c.
    
    This results in the error message below for MinGW hosts:
    error starting child process '| <executable> <args>': CreateProcess: No such file or directory
    
    This commit add the missing '|' detection and removal to ser-mingw.c.
