This reverts commit 41ee4d698fd87085494ceeec1985a2b99222c5b0.
Fix compilation failure on our containers:
../tests/intel/xe_exec_system_allocator.c: In function test_exec:
../tests/intel/xe_exec_system_allocator.c:1210:21: error: MREMAP_DONTUNMAP undeclared (first use in this function); did you mean DONTUNMAP?
remap_flags |= MREMAP_DONTUNMAP;
