RMX1971: Update kernel target level

Updating kernel target level to Android Q

checkvintf Error
checkvintf E : files are incompatible:
    Runtime info and framework compatibility matrix are
    incompatible: Kernel FCM version is not specified, but kernel version
    4.9.337 is found. Fix by specifying kernel FCM version in device
checkvintf E : manifest. For example, for a *-r kernel:
checkvintf E : <kernel target-level="4"/>
checkvintf E : INCOMPATIBLE
