vold: restore 4.4 sdcard logic

Mount points in 4.4 are always fuse-wrapped to provide granular
permission. Unix file systems no longer need to be manually
fuse-wrapped by us.

vold: Add selinux support to ext4

Squashed commit of the following:

Author: Pawit Pornkitprasan <p.pawit@gmail.com>
vold: mount ext4 with forced SELinux context

Always mount voldmanaged ext4 partitions with the SELinux sdcard_external
context. For other file systems, this is done via the genfs_context,
but since ext4 supports SELinux natively, it must be set here.

vold: force SELinux context only for sdcard

Google uses this code to mount ASEC as well and we shouldn't force
their SELinux contexts

in the fstab as 'auto').

f2fs: disable fsck check

fsck.f2fs does not fix any inconsistencies "yet".

Disable fsck routine as this is just wasting time consumed to mount f2fs volumes.

The kernel can determine if a f2fs volume is too damaged that it shouldn't get mounted.

We should wait for f2fs-tools version higher than v1.3.0.
(fsck.f2fs for fixing inconsistencies is a work-in-progress)
