ANDROID: update the kernel release format for GKI
The new kernel release format is: w.x.y-zz-k where,
w.x.y are the current values
zzz is the Android Release value
k is the KMI Generation number
This allows one to identify the kernel module interface version using
`uname -r`. The KMI Generation number is used to identify any KMI
changes that occur after the KMI freeze. This should only occur in an
unlikely event that a security patch requires a KMI update.
Here is a local example:
5.4.51-android12-0-00153-ga972f59040e4-dirty
