Revert "ltp: syscalls: mlock: Fix fault granularity"

This reverts commit a2b6c319bc7195b74256746a3f5d6a42c7039d85.

Reason: 16KB x86_64 now emulates the mincore() syscall, so revert the
tests to their original versions.

Bug: 390505059
Test: atest vts_ltp_test_x86_64:syscalls.mlock201_64bit#syscalls.mlock201_64bit
