Add 'g++.target/nvptx/alias-g++.dg_init_dtor2-1.C'

... as one minimized example for the issue that with nvptx '-malias' enabled
(as implemented in commit f8b15e177155960017ac0c5daef8780d1127f91c
"[nvptx] Use .alias directive for mptx >= 6.3"), there are hundreds of
instances of link-time 'unresolved symbol [alias]' across the C++ test suite,
which are regressions compared to a test run with (default) '-mno-alias'.

	PR target/104957
	gcc/testsuite/
	* g++.target/nvptx/alias-g++.dg_init_dtor2-1.C: Add.
