update_engine: Add support for parsing the size of a squashfs.
This patch extends the utils::GetFilesystemSize() function to support
squashfs (in addition to the existing ext3 support). The filesystem
type is detected automatically.
squashfs doesn't define a block size for the physical device that it
relies on. There's a definition of block size for the data before
compression that doesn't affect the block size used for the underlying
device. When creating the squashfs, it is by default padded to 4 KiB,
so we assume 4 KiB as the block size. This is also the minimum block
size required by verity to compute hashes in all supported archs.
BUG=chromium:430956
TEST=Unittest added.
