Jiapeng Chong 9ba3462c1c perf tests: Fix an incorrect type in append_script() ...

The return value from the call to readlink() is ssize_t. However, the
return value is being assigned to an size_t variable 'len', so making
'len' an ssize_t.

./tools/perf/tests/tests-scripts.c:182:5-8: WARNING: Unsigned expression compared with zero: len < 0.
