[PATCH 3/5] rpdfs-progs: rename utask asm extraction file to dodge save-temps race

CFLAGS includes -save-temps, so compiling utask/utask.o produces
utask/utask.s as a side effect.  This collides under make -j with
the explicit rule that generates the same file to grep UTASK_ASM
defines from.  Use a separate filename for the extraction.
