libbpf: Fix uretprobe.multi.s programs auto attachment
As reported by Andrii we don't currently recognize uretprobe.multi.s
programs as return probes due to using (wrong) strcmp function.
Using str_has_pfx() instead to match uretprobe.multi prefix.
Tests are passing, because the return program was executed
as entry program and all counts were incremented properly.
