selftests/ftrace: Use long for synthetic event probe test
On 32bit the trigger-synthetic-eprobe.tc selftest fails with the error:
hist:syscalls:sys_exit_openat: error: Param type doesn't match synthetic event field type
Command: hist:keys=common_pid:filename=$__arg__1,ret=ret:onmatch(syscalls.sys_enter_openat).trace(synth_open,$filename,$ret)
^
This is because the synth_open synthetic event is created with:
echo "$SYNTH u64 filename; s64 ret;" > synthetic_events
Which works fine on 64 bit, as filename is a pointer and the return is
also a long. But for 32 bit architectures, it doesn't work.
Use "unsigned long" and "long" instead so that it works for both 64 bit
and 32 bit architectures.
