There's a report that newly added --rootdir print too many warnings for
hardlinks, which is maybe not that uncommon. We still want to let the
user know about that so print it just once and count how many were
found:
$ mkfs.btrfs --rootdir ...
WARNING: '/tmp/btrfs-progs-mkfs-rootdir-hardlinks.7RcdfR/rootdir/inside_link' has extra hardlinks, they will be converted into new inodes
WARNING: 12 hardlinks were detected in /tmp/btrfs-progs-mkfs-rootdir-hardlinks.7RcdfR/rootdir, all converted to new inodes

The test case will create the following directory layout:
.
|- rootdir/
| |- inside_link
|- outside_link
Both inside_link and outside_link are hard links of each other.
And use rootdir/ as the rootdir for mkfs.
This is to ensure the nlink of inside_link is correctly set to 1.
Inspired by the recent rework which fixes the handling of hard links.
