git: use COPY_ARRAY and MOVE_ARRAY in handle_alias()
Use the macro COPY_ARRAY to copy array elements and MOVE_ARRAY to do the same for moving them backwards in an array with potential overlap. The result is shorter and safer, as it infers the element type automatically and does a (very) basic type compatibility check for its first two arguments. These cases were missed by Coccinelle and contrib/coccinelle/array.cocci because the type of the elements is "const char *", not "char *", and the rules in the semantic patch cautiously insist on the sizeof operator being used on exactly the same type to avoid generating transformations that introduce subtle bugs into tricky code.
