Verify in ttyname() that the symlink is valid

This patch verifies the path resulting from reading the symlink in
/proc/self/fd is valid and refer to the same inode as the file descriptor.  If
the original path is unreachable, try if the path from the global root is valid
from this context as well.  If not valid, then fall back to iterating through
the device files under /dev.
