scanner: drop altmacro from dtddata.S

Stop using .altmacro in dtddata.S, because clang does not yet implement
it. Turns out that we do not actually seem to need it, and we can modify
the syntax to work without it.

Moving the double quotes from the binfile line to the .incbin line is
required to avoid the assembler error "missing string". Instead of & we
now use \() to mark the end of macro argument name.
