fs: proc: cmdline: Patch SafetyNet flags

Userspace parses androidboot.* flags from /proc/cmdline and sets the
ro.boot.* props accordingly, which in turn trips SafetyNet when the
reported values are incorrect.

Patch the cmdline flags checked by SafetyNet to prevent it from failing
a device. These flags were found by extracting the latest snet.jar and
searching for 'ro.boot.' strings.
