Aneesh Kumar K.V 71013d071b selftest/vm: fix map_fixed_noreplace test failure 
[ Upstream commit f39c58008dee7ab5fc94c3f1995a21e886801df0 ]

On the latest RHEL the test fails due to executable mapped at 256MB
address

    Error: couldn't map the space we need for the test

Fix this by finding a free address using mmap instead of hardcoding
BASE_ADDRESS.
