Use the fscrypt key removal notifier chain to make sdcardfs evict its
dentries when an fscrypt key is about to be removed. This is needed for
the FS_IOC_REMOVE_ENCRYPTION_KEY ioctl to properly "lock" the encrypted
files underneath sdcardfs when an Android user is stopped.
Test: pm create-user 10
am start-user 10
find /data/media/10/ # filenames are in plaintext form
am stop-user 10
find /data/media/10/ # filenames are in ciphertext form
(But currently the kernel and vold still warn about other files
still being open, due to b/140762419)
