snan tests: Avoid test failure on Android.

[Collin Funk]

Hi Bruno,

I see the following test failure on Android 16 after building a testdir
of all modules:

    $ cat gltests/test-snan-1.log 
    test-snan-1.c:99: assertion 'fetestexcept (FE_INVALID)' failed
    Aborted
    FAIL test-snan-1 (exit status: 134)

Here is what I ran ./configure with:

    $ ./configure CC='clang -target aarch64-unknown-linux-android28'
    $ make check

My understanding is that Bionic imports all it's math functions from the
BSDs. Based on the symbols this case looks like same as why
FreeBSD/arm64 fails:

    $ nm ./gltests/test-snan-1 | grep -F __addtf
    0000000000008d0c T __addtf3

Okay to disable this test with the attached patch?

Collin
