cryptohome: create tracked subdirectories before mounting ecryptfs

In b/115997660, files created behind ecryptfs' back are not
initially visible: this is probably because a negative ecryptfs
dentry doesn't effectively get revalidated.

Instead, create pass-through directories before mounting.
This should ensure that at the time of setting up the
ecryptfs mount, all of the tracked directories are still
present.

BUG=b:115997660
TEST=login with ecryptfs, unittests.
