Only primary external storage is writable.

Verify that mount points not representing primary external storage
do not allow writing.  Apps are still allowed to write to package-
specific directories on secondary storage devices, as verified by
testAllPackageDirsWritable().

More tests to verify getStorageState() behavior.  Handle missing
secondary external storage devices with null checks.
