Replace cmdline to pass SafetyNet (no SN Issues allowed) 

Userspace parses this and sets the ro.boot.verifiedbootstate prop
according to the value that this flag has. When ro.boot.verifiedbootstate
is not 'green', SafetyNet is tripped and fails the CTS test.

Change verifiedbootstate from /proc/cmdline in order to fix the failed
SafetyNet CTS check.
