[parted-devel] labels/*.c: Declare some static arrays to be "const".

[Jim Meyering]

Making these tables "const" lets the compiler/linker put the values
in read-only storage.  Not only more efficient in some cases, but
also protects against accidental modification.

	Declare some static arrays to be "const".
