This change allows the `vma_map` and `vma_create_map` syscalls to map to addresses other than the one specified, and therefore makes the address parameter to those syscalls `inout` in order to return the mapped address. Also add the `exact` flag for specifying that mapping needs to be done at the exact address given. If the mapping collides with another, the new `j6_err_collision` error is returned.
