Squashed commit of the following:

Summary:
* build static e2fsprogs
change makefies to build static mke2fs and tune2fs and place them in
$(PRODUCT_OUT)/utilities

* static e2fsck, tune2fs, and mke2fs for recovery

* Fix dev time initialization for cache age caculation

* dev->bid_time was initialized to INT_MIN causing an
overflow in cache age calculation, which in turn
caused a new device structure to not be filled with
data due to assumed up-to-date values.

* blkid: Add support for probing exFAT
 * e2fsprogs can't currently detect exFAT filesystems.
 * Apply patch from GoogleTV to add support.

Test Plan: Win
