testsuite: Add necessary dejagnu directives to pr115815_0.c
I have received an email from the Linaro infrastructure that the test
gcc.dg/lto/pr115815_0.c which I added is failing on arm-eabi and I
realized that not only it is missing dg-require-effective-target
global_constructor but actually any dejagnu directives at all, which
means it is unnecessarily running both at -O0 and -O2 and there is an
unnecesary run test too. All fixed by this patch.
I have not actually verified that the failure goes away on arm-eabi
but have very high hopes it will. I have verified that the test still
checks for the bug and also that it passes by running:
make -k check-gcc RUNTESTFLAGS="lto.exp=*pr115815*"

* gcc.dg/lto/pr115815_0.c: Add dejagu directives.
