    [gdb/testsuite] Normalize gdbserver path name
    
    Currently for the target board remote-gdbserver-on-localhost we use the
    gdbserver file on build, using a file name which includes "/../".
    
    Fix this by using a normalized file name instead.
    
    This allows us to be more restrictive about which files REMOTE_TARGET_USERNAME
    can access:
    ...
    -    remote_exec build "chmod go-rx $objdir/outputs"
    +    remote_exec build "chmod go-rx $objdir"
    ...
    
    Tested on x86_64-linux.
