cryptohome: Fix GetAccountDiskUsage() count file size twice.

/home/.shadow/$hash, which contains /home/.shadow/$hash/mount/user (bind
mounted to /home/user/$hash), and /home/.shadow/$hash/mount/root (bind
mounted to /home/root/$hash), is counted together with /home/root/$hash
and /home/user/$hash, thus causing the final calculated size to be off
by a factor of 2.

BUG=b:151092607
TEST=tast run $dut hwsec.AccountDiskUsage && unit tests
