This let's systemd-repart respect the `SOURCE_DATE_EPOCH` environment variable when creating directories in the local tree through `CopyFiles` or `MakeDirectories`. To do this, we pass a timestamp `ts` to `mkdir_p_root`, which it will use to fix up `mtime` and `atime` of the directory it creates as well as the `mtime` of the directory it creates the other directory *in*, as the `mtime` of the latter is modified when creating a directory in it. For the same reason, it also needs to fixup the `mtime` of the upper directory when copying a file into it through `CopyFiles`. If `SOURCE_DATE_EPOCH`, times are left as is. (`UTIME_OMIT`)
