Subject: makepkg: use --apparent-size when du supports it

Amazingly, using "sleep 1" to convince btrfs to report correct file
sizes is only a 90% fix.  Sometimes more sleep is needed.

Instead we use the --apparent-size argument to du to get actual file
sizes. This is used only on Linux as the various BSDs do not support
this argument.
