tools string: Use __fallthrough in perf_atoll()
The implicit fall through case label here is intended, so let us inform
that to gcc >= 7:
CC /tmp/build/perf/util/string.o
util/string.c: In function 'perf_atoll':
util/string.c:22:7: error: this statement may fall through [-Werror=implicit-fallthrough=]
if (*p)
^
util/string.c:24:3: note: here
case '\0':
^~~~
