scanner: Replace #define tab with space
wayland-client-protocol.h and wayland-server-protocol.h use a tab
between the identifier and token of generated #defines for request/event
opcodes and versions. While this sometimes enables vertical alignment,
it more frequently doesn't, and leads to awkward spacing.
Replace the tab with a space, for consistency and readability.
