perf trace: Set errpid to false for rseq and set_robust_list

JIRA: https://issues.redhat.com/browse/RHEL-78308

description
===========
The 'rseq' and 'set_robust_list' syscalls don't return a pid, so set
errpid for both to false.

Fixes: 0c1019e ("perf trace: Mark the 'rseq' arg in the rseq syscall as coming from user space")
Fixes: 1de5b5d ("perf trace: Mark the 'head' arg in the set_robust_list syscall as coming from user space")

[ Remove explicit .errpid = false, omitting its initialization zeroes it, as noted by Namhyung ]
