Fix USB mount issue after GOTA upgrade

After upgrading GOTA, the Netlink buffer size was too small to receive all uevents, resulting in the "NetlinkListener: recvmsg failed (No buffer space available)" error and increasing the chance of USB mount failure. Increased the Netlink buffer size to resolve this issue.

Test Steps:
1. Upgrade with GOTA.
2. Reboot the system with the USB connected.
3. Verify that the USB device is detected correctly.
