vold: set klog level so e2fsck output is logged

When mounting an encrypted filesystem vold calls fs_mgr, which
will call e2fsck on the fielsystem if it's configured to, and
fs_mgr will attempt to log the output the kernel log. However,
if won't log anything unless the klog level is set to 6, aka INFO.
