[clang][NFC] Remove alignment checks from test/CodeGen/c-strings.c (#196501)

and re-enable it on more targets.

I don't think this test was intended to check for alignment. Those
expectations were added as part of FileCheck-izing the test in
e29dadb6403c8b0d3658f9bbbe2f5fbde5431fdb and we've been working around
them or xfailing the test since.
