    testsuite: Define _POSIX_SOURCE for tests [PR113278]

    As the tests assume that fileno() is visible (only part of POSIX),
    define the guard to ensure that it's visible.  Currently, glibc appears
    to always have this defined in C++, newlib does not.

    Without this patch, fails like this can be seen:

    Testing analyzer/fileno-1.c,  -std=3Dc++98
    .../fileno-1.c: In function 'int test_pass_through(FILE*)':
    .../fileno-1.c:5:10: error: 'fileno' was not declared in this scope
    FAIL: c-c++-common/analyzer/fileno-1.c  -std=3Dc++98 (test for excess e=
rrors)

    Patch has been verified on Linux.
