LOG: [compiler-rt][ubsan][test] Fix TypeCheck/misaligned.cpp on Sparc

Two ubsan tests FAIL on Sparc:

  UBSan-Standalone-sparc :: TestCases/TypeCheck/misaligned.cpp
  UBSan-Standalone-sparcv9 :: TestCases/TypeCheck/misaligned.cpp

I've reported the details in Bug 47015, but it boils down to the fact that
the `s1` subtest actually incurs a fault on strict-alignment targets like
Sparc which UBSan doesn't expect.

This can be fixed like the `w1` subtest by compiling with
`-fno-sanitize-recover=alignment`.

Tested on `sparcv9-sun-solaris2.11`, `amd64-pc-solaris2.11`, and
`x86_64-pc-linux-gnu`.
