Since 7b76d6bf221 (Makefile: add and use the ".DELETE_ON_ERROR" flag,
2021-06-29) we don't need to guard the clobbering of $@ with this sort
of "mv $@+ $@" pattern in these cases where we're merely generating a
file that'll be used as a dependency for other files, as in this case
for GIT-PERL-HEADER.

.DELETE_ON_ERROR is, as far as I know, a GNUism. Does building git require
the use of GNU make?

Yes, we've had a hard dependency on GNU make for forever, and already
use .DELETE_ON_ERROR, this is just moving it around.
