[OpenMP] Add map clause to the LIT test on use_device_addr clause

As per the OpenMP Spec, "A list item in a use_device_addr clause
must have a corresponding list item in the device data environment"
. Therefore a `map` clause is added which will make sure that the
respective list items are mapped to the device data environment
before the `use_device_addr` clause is specified. The CHECK lines
are also modified based on this change.
