[PATCH] D29706: [libcxx] [test] Fix hard_link_count test to account for fs with dir nlink==1

[Michał Górny via Phabricator via cfe-commits]

mgorny created this revision.

Filesystems are not required to maintain a hard link count consistent
with number of subdirectories. For example, on btrfs all directories
have nlink==1. Account for that in the test.
