Fixed LIT regression from an outdated testcase

This CL fixed LIT test regression by adding local_unnamed_addr attribute
to expected global variable declarations in P_array_init/array_init.rs.
The added attribute apparently is not significant as far as the test is
concerned; was likely introduced by recent slang rebasing.

Test: slang lit-tests with DISABLE_NDEBUG
