lib/test_ubsan.c: make test_ubsan_misaligned_access() static

test_ubsan_misaligned_access() is local to the source and does not need
to be in global scope, so make it static.

Cleans up sparse warning:

  lib/test_ubsan.c:91:6: warning: symbol 'test_ubsan_misaligned_access' was not declared. Should it be static?
