dpkg-split: Use a constant expression to declare an array

Although usually the compiler should replace strlen(literal) with a
built-in, it might not, and it's more predictable to use a constant
expression using sizeof() instead to avoid making it a variable
length array. This fixes a warning with latest gcc and -Wvla.
