selftest/bpf: Fix kprobe_multi bench test
With [1] the available_filter_functions file contains records
starting with __ftrace_invalid_address___ and marking disabled
entries.
We need to filter them out for the bench test to pass only
resolvable symbols to kernel.
[1] commit b39181f7c690 ("ftrace: Add FTRACE_MCOUNT_MAX_OFFSET to avoid adding weak function")
