perf evlist: Explicititely initialize input_name
It was a global variable, so it was initialized, implicitely, to zero by
being placed in the bss.
Now it is just a local variable that is then passed to the __cmd_evlist
routine, so it must be explicitely set to NULL.
The problem manifested on a Fedora 17 system, using:
gcc version 4.7.0 20120507 (Red Hat 4.7.0-5) (GCC)
But not on several other systems, by luck.
