perf_counter tools: Work around warnings in older GCCs
GCC 4.1.2 produces:
util/parse-options.c: In function ‘get_value’:
util/parse-options.c:36: warning: ‘arg’ may be used uninitialized in this function
builtin-top.c: In function ‘display_thread’:
builtin-top.c:178: warning: ‘printed’ may be used uninitialized in this function
Annotate them away by initializing these variables to 0.
