Subject: [PATCH] dre: init: Mlock limited to 64 KB

In Android 14 and higher, the platform reduces the maximum
memory that can be locked using mlock() to 64 KB per process.
In previous versions, the limit was 64 MB per process.
The new restriction promotes better memory management
across apps and the system.

Test: CtsInitTestCases#MemLockLimit
