fs: Lower reclaim segment and threshold

• Xiaomi's default segment reclamation (4096), along with that of other OEMs, is designed for MIUI, HyperOS's, and other $hit stocks roms.
  heavy I/O patterns (background services, frequent writes).
  For AOSP: 1. Lower Overhead: Smaller Garbage Collection (GC) batches
               reduce CPU/storage load.
            2. Better Responsiveness: Avoid long GC pauses during light
               usage.
            3. Battery Savings: Less aggressive reclaiming reduces
               power spikes.
