makepkg: do not count hard links multiple times when calculating pkg size
Exclude files with hardlinks when cat'ing all the files, and do a second run to look at each file with hardlinks, keep track of the ones we've already operated on, and only cat each inode once. Then use "wc -c" to get the size of all (deduplicated) files the same way we were already doing.
