getline() is considered as undeclared in util/util.c because
it includes string.h, that in turn includes stdio.h, without
having defined _GNU_SOURCE.
But util.c also includes util.h that handles the _GNU_SOURCE and
all the needed inclusions already. Let's include only util.h
and sys/mman.h which is the only one header not handled by
util.h
This fixes the following build error:
util/util.c: In function 'slow_copyfile':
util/util.c:49: erreur: implicit declaration of function
'getline' util/util.c:49: erreur: nested extern declaration of 'getline'
