    [testsuite] Require c99_runtime to run builtin-sprintf.c
    
    On nvptx, I run into an execution failure in test-case
    gcc.dg/tree-ssa/builtin-sprintf.c because the test-case uses the 'hh'
    modifier.
    
    The port uses newlib, which does by default not support that modifier.
    There's a configure option --enable-newlib-io-c99-formats to enable this
    support, but that requires alloca support, which nvptx doesn't have.
    
    Fix this by requiring c99_runtime for running the test-case.
    
    Tested on nvptx.

            dg-do run.
