[Ada] Align arrows in parameter associations

[Pierre-Marie de Rodat via Gcc-patches]

Whitespace cleanup; wrong layout found with grep.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

        * exp_ch4.adb (Expand_N_Op_Ne): Fix whitespace.
        * sem_dim.adb (Expand_Put_Call_With_Symbol): Likewise.
        (Reduce): Likewise.
