dpkg: Use utimes(2) instead of obsolete utime(2)

POSIX.1-2008 marked utime(2) as obsolete. Ideally we'd switch to use
utimensat(2), which would simplify quite a bit the code, but it's not
yet widely available, and using it would imply having to support
fallback code at compilation and run-time. This can be done later on
once we up the POSIX baseline.
