[testsuite] Remove explicit -O2 from gcc.c-torture/compile/pr44686.c

[Martin Jambor]

Hi,

I'm about to check in the following as obvious.  The explicit -O2
defeats the different O levels the torture mechanism tries.

Tested on x86_64-linux by running 

make -k check RUNTESTFLAGS="compile.exp=pr44686.c"

and verifying all tests passed.

Thanks,

Martin
